Acceleration....Getting You Up to Speed!

Thanks to our outstanding demonstrators (Nick C. and Georgie!), we were able to get this cool shot of "Newton's apple" dropping. And thanks to some clever engineering by Casio, we see five different images stitched into one. Important: the SAME amount of time elapses between each image of the apple.
So, what does it mean to ACCELERATE?! There are several different points of the ball's location in each image. In your own words, respond to the two following questions:
1. What's different about the ball's velocity in at each point where it appears in the image?
2. Why is there more distance between each point where the ball appears in the image?
(Show me that you understand the concepts of velocity and acceleration by being detailed in your response!)

  1. 1. The ball is falling in one direction and the speed is growing.
    2. There is more distance between each point where the ball appears because it is gaining speed as it falls, so it covers more distance in less time.

  2. 1. The balls velocity is different at each point in the picture because it is falling because if gravity.
    2. Because the ball is gaining speed.

  3. 1. The difference in the balls velocity is that the apple is gaining speed as it falls.
    2. There is more distance between each point where the ball appears in the image because it is covering more distance as it falls. It is also gaining speed.

  4. 1. The balls velocity increased as the ball falls due to gravity.

    2. There is more space between each ball because the call is accelerating because of gravity.

  5. 1. The velocity of the ball is increasing in each picture as it falls farther and farther becasue of gravity.

    2. There is a greater distance between each picture because the ball is accelerating so the speed is increasing.

  6. 1. In the first Photograph, the apple's velocit is increasing as it gets closer and closer to the ground, because of gravity.

    2. The ball is traveling at a greater speed (more velocity), so it begins to cover more distance in less amount of time.

  7. 1. When the Ball is first dropped from the origin it starts to fall at a certain rate. This rate increases the more it falls due to gravity pushing the ball down. Basically the more it falls the more it accelerates.

    2. There is more distance between each shot because the ball accelerates so it falls at a faster rate in less time.

  8. 1. Gravity allows the ball to increase its speed from when it falls down all the way to the point that it touches the ground.

    2. The closer the ball gets to touching the ground, the faster the ball accelerates as it gains speed through gravity.

  9. 1.Velocity Is speed in a specific direction. At each point, the direction of the ball does not change but the speed increases the closer the ball gets to the floor. The velocity is changing.

    2. Acceleration is the change in velocity, in either speed or direction.
    The reason there is more distance is because as the ball is falling, its acceleration is increasing due to gravity. As velocity changes it creates acceleration.

  10. 1) The ball is falling in one direction and it's velocity quickly gains speed as it is being pulled downwards by gravity.

    2) There is more space between the balls because it gains distance due to acceleration

    ReplyDelete
  11. 1. The direction of the ball does not change; however, as it gets closer to the ground, the speed increases.

    2. There is more distance between each point because the ball is accelerating in speed.

  12. 1. At the point of the release, gravity does not have a big impact on the apple, but the farther down it goes, the more gravity has an effect, increasing the velocity as well as the acceleration of the apple.

    2. As the apple accelerates more, the faster the speed if the apple being dropped, which is why there are different distances between the different pictures

  13. 1. The ball is accelerating the further it goes down. While the velocity is increasing, gravity pulls it down even further.

    2. As the ball drops down more and more the acceleration increases on its way down.

    ReplyDelete
  14. 1.) As the apple is being dropped, the speed increases as it goes down and the direction stays the same.

    2.) There is more distances between each ball because the acceleration is increasing as the ball gets closer to the ground causing more distance.

    ReplyDelete
  15. 1. When the ball is released it falls slowly, however once it gets closer to the ground then the ball falls a lot faster. Moreover, the velocity increased as the ball got closer to the ground.

    2. Within the picture the apple's acceleration is similar in the first two points after that the ball accelerates much faster than originally.

    ReplyDelete
  16. 1. When the apple drops, the direction is constant because the apple goes straight to the floor. the speed increases because the gravitational pull becomes much stronger as the apple becomes closer to the floor.

    2. The apple accelerates and gains more speed after being dropped. Therefore, over a certain amount of time the apple is traveling more distance due to the speed.

    ReplyDelete
  17. 1) The speed with which the ball drops increases because the object is already in motion and as gravity pulls it to the ground, its speed increases as it accelerates

    3) Since the ball continues to fall faster and faster, it is because the acceleration increases as it stays in motion. the speed with which the ball travels faster changes, which is why the ball gets farther and farther as it accelerates towards the ground faster.

  18. 1. The longer the ball falls, the more it accelerates because of gravity pulling down on it with stronger force, the closer it gets to the ground.

    2. There is more distance between each point because the ball's speed became faster as it fell.

    ReplyDelete
  19. 1.As the ball falls closer and closer to the floor the gravitational pulls increases

    2. The distance between the ball In the picture gets bigger because the ball is accelerating and increasing speed.

    ReplyDelete
  20. 1. Gravity is pulling the ball to the ground and it's also accelerating.
    2. The ball is increasing in speed and therefore the distance between each picture is also increasing.

  21. 1. As the ball falls to the ground, gravity pulls it down faster the longer time its spends in the air.

    2. The distance between each point is caused by the amount of speed making intervals as it goes farther to the ground.

    ReplyDelete
  22. 1) The ball is falling towards the ground and gradually getting faster.

    2) There is more distance in the same amount of time thus telling us that the speed is increasing.

    ReplyDelete
  23. 1. The ball's velocity increases as it gets closer to the ground.

    2. The ball is getting gradually faster as it gets closer to the ground.

    ReplyDelete
  24. 1. The balls velocity increases as it goes towards the ground because as more time elapses, the ball gains speed.

    2. The distance between the ball is increasing as it nears the ground because even though the same amount of time elapses between each interval, the increasing velocity covers a greater distance.

    ReplyDelete
  25. 1. There is an increase in the ball's velocity due to the gravitational pull that is imposed on the ball.

    2. The longer the ball falls, gravity pulls the ball more to the floor.

    ReplyDelete
  26. 1. The balls velocity increases as its falling down because as more time goes by, gravity pulls it down gaining the apple more speed.

    2. There is more distance between each point because the speed is increasing, so time goes by between each point causing velocity and gravity to pull the apple down further.

    ReplyDelete
  27. 1. The velocity of the ball is constantly increasing as time progresses; however, the acceleration is staying at the constant rate of gravity which is 22 mph. As the ball falls, the velocity is increasing and moving faster.

    2. There is more distance because velocity is increasing which causes the ball to move a greater distance in a shorter span of time.

    ReplyDelete
  28. 1. The direction of the ball stays the same, but the speed in which gravity is pulling the ball down increases at as time goes on.

    2. There is more distance between each point because of the acceleration of gravity. Gravity's force becomes stronger as time passes because at a constant rate, the velocity is changing (acceleration).

    ReplyDelete
  29. 1) As the ball falls closer to the floor, gravity is more effective, therefore increasing the speed or velocity.

    2) There is more distance between each point where the ball appears in the image because the ball is accelerating in speed or velocity, which covers more distance in less time.

    ReplyDelete
  30. 1. The initial velocity before the ball has dropped is 0, but as the ball falls the velocity increases due to gravity.

    2. As the ball drops, the velocity increases due to gravity; therefore, the ball covers more distance in less time which explains why there is greater distance between each picture of the ball.

    ReplyDelete
  31. 1. The ball's velocity increases as it gets closer to the ground.
    2. There's more distance between each point because the ball is accerlating more.

    ReplyDelete
  32. 1. The balls velocity increases as it begins to drop more and more to the floor because of its gravitational pull.
    2. There is a greater distance because as the velocity builds the ball moves faster in a shorter amount of time.

    ReplyDelete
  33. 1. The balls direction is saying the same however the balls speed is increasing over time as gravity takes more effect.

    2. There is more distance between the apple in each still because as your velocity increases with time so does your acceleration, so the apple moves a farther distance between each still.

    ReplyDelete
  34. 1) the balls velocity is increasing as the direction is moving down however the speed is increasing which leads to 2) with the ball accelerating at 22mph/sec effectively doubling the speed with each second

    ReplyDelete
  35. 1. The ball's velocity is increasing as it falls farther down because gravity increases it's speed the longer the ball is in the air.

    2.There is a greater distance the closer the apple gets to the floor because the more gravity comes into effect, the more that the ball accelerates/ moves faster.

    ReplyDelete
  36. 1) The direction of the ball is the same all the way down, but as time goes on, the effect of gravity causes the velocity to increase, which in turn increases the speed of the ball.

    2) The distance of the ball increases between each picture because the ball is accelerating at twice the rate because that is the rate at which gravity exists.

    ReplyDelete
  37. 1) The velocity of the ball increases due to gravity's effect on it, causing its speed to increase.
    2)The distance increases between each point because the ball is accelerating, again due to gravity

    ReplyDelete
  38. 1. At each point the balls velocity increases due to gravity.

    2. There is more distance between each point where the ball appears because it is covering more distance as it falls because of the gain in speed.

    ReplyDelete
  39. 1. The balls direction stays the same, but the speed increases because gravity pulls the ball downwards.
    2. As the ball falls, the rate at which it accelerates is faster causing it to cover more distance in a shorter amount of time.

    ReplyDelete
  40. 1. The ball's velocity increases as gravity takes effect.

    2. There is more distance between each still because the acceleration increases when the velocity increases over time.

    ReplyDelete
  41. 1. The ball continues to move downward, however as it falls closer to the ground gravity is causing the ball to gain more momentum and drop quicker.
    2. There is more distance in between because the ball is gaining momentum and speed, which results in the ball covering more space in a shorter amount of time.

    ReplyDelete
  42. 1) As the ball fall down to the ground the velocity increases as it takes on gravity.
    2) Because as the ball fall down the speed increases so it is able to move through more space quicker.

    ReplyDelete
  43. 1. The longer the ball falls, the faster it goes.

    2. There is a bigger distance because as the ball falls, the faster it goes.

    ReplyDelete
  44. 1. Gravity is pulling the ball towards the floor with increasing velocity in each picture.

    2. The ball is increasing its velocity causing the ball to gain a greater distance between each picture.

    ReplyDelete
  45. 1. The ball is gaining speed as it falls to the floor due to gravity

    2. The more the ball falls, the more distance is covered, as well as the amount of speed that is increasing.

    ReplyDelete
  46. 1. As more time elapses, the speed that the ball drops at increases because of continuous acceleration.
    2. Because the force of gravity makes the ball accelerate at approximately 9.8 m/s the speed and velocity of the ball is always increasing causing greater gaps between images.

    ReplyDelete
  47. 1.As time passes, the ball drops at a faster rate because gravity is pulling it down and increasing the acceleration.
    2. As the ball drops the acceleration increases causing there to be more distance between each point in the image.

    ReplyDelete
  48. 1.Velocity is the speed in a certain direction. The ball’s velocity increases at every point in the picture because of gravity pushing the ball down.
    2. Acceleration is the rate at which an object changes velocity. There is more distance between each point where the ball appears in the image because the ball accelerates faster, which causes a greater distance between each ball.

    ReplyDelete
  49. 1. Since gravity is constantly changing, the ball's speed as well as acceleration, as it gets closer to the ground, increases.

    2. Gravity makes the ball accelerate faster as in gets closer to the ground. Because of this, the ball is getting faster, creating bigger gaps in between the spaces of the stitched pictures.

    ReplyDelete
  50. 1. As the ball approaches the ground, gravity continuously increases its speed. As such, the difference in the velocity of the ball at each point in the image is that the ball's velocity increases in speed as it nears the ground.
    2. The reason for the increasing distance between each point in the image is that as the ball falls, gravity continuously accelerates it, causing its velocity to increase. Therefore the ball will cover a greater and greater distance in the time it takes for the camera to take each consecutive picture.

  51. 1. When the ball first drops, it is at a starting speed of 0mph. Gravity pushes the ball down causing the speed in which the ball travels to accelerate, but the velocity stays the same because the ball is still moving downwards the whole time.
    2. Gravity forces the ball downwards and makes the ball travel towards the ground faster, making the gaps between each picture bigger and bigger because each time a picture is taken, the ball has already moved a lot.

    ReplyDelete
  52. 1.The ball is accelerating and moving faster while the velocity is also increasing. The gravitational pull also progressively becomes stronger.
    2. There is more distance between each point where the ball appears in the image because of gravity, which causes the ball to move faster as it falls. Therefore, the ball accelerates and falls a larger distance in the same amount of time.

    ReplyDelete
  53. 1. The velocity is increasing, because the speed is increasing due to the force of gravity.
    2. The ball is constantly accelerating, at an increasing rate

    ReplyDelete
  54. 1. The velocity is increasing which makes the ball go faster and cover more distance. Gravity pulls the ball which also affects how long it takes to hit the ground.
    2. The ball falls at the same speed and direction due to the force of gravity.

    ReplyDelete
  55. 1. The balls speed increases as gravity takes its toll on the ball while the direction does not change and stays the same
    2. The distance varies in each shot because the velocity continues to increase as a result of gravity, and as the ball begins to gain momentum the acceleration enhances and moves the ball downward quicker.

    ReplyDelete
  56. 1. The ball's velocity is increasing as it falls
    2. The distance is greater because the ball is accelerating at a steady rate

    ReplyDelete
  57. 1. The apple’s speed increases as gravity pulls it farther down. While the direction of the ball stays the same (velocity is speed in a direction), the velocity increases as the apple falls to the floor.
    2. There is more distance between the apple(s) in the images because as it is dropped, it will cover more distance in a shorter span of time due to a gravitational pull. The closer the apple gets to the floor, the faster it goes.

    ReplyDelete
  58. The balls velocity increases at 22mph/ sec downward in each image.
    Therefore, the ball reaches its slowest velocity when just released and its fastest velocity right before it hits the ground.

    ReplyDelete
  59. 1. Gravity caused the ball to go downward and drags it down to the ground at 22/mph/sec. The speed increases and it goes downward.
    2. The balls distance increases while it stays at a constant and steady rate of speed.
