Ball Bearing Speed Record

Planning

        I am going to investigate how the height of a ramp effects the speed of a bearing ball that is dropped form the top of the ramp.

        I predict that the higher the ramp, the faster the ball will go. I think this is because as the ramp goes higher, the ball will be dropped higher, therefore there will be more gravitation potential energy the ball will have, making the ball goes faster as it will be transferred into kinetic energy toward the end.

        To back this theory, I will calculate the speed of the ball, (speed = distance – time). Also I will calculate the gravitation potential energy, (mass x gravity x height) and also the kinetic energy, (1/2 x mass x speed). I will use the results of the calculation to compare and to see if my prediction is correct.

        I will use the following equipments for my experiment:

  • A ball bearing
  • A ramp
  • A stopwatch (to time)
  • A ruler (to measure the heights of the ramp)
  • A scale (to weigh the ball bearing)

To make this experiment more accurate, I will do each experiment three times, then I will do the average for the speed. I will need to make sure that I have the same equipments if I would do this experiment on two different days. If I am going to this experiment on different day, I will need to make sure that the ball bearing is the weight and that the same person would do it, e.g. the person that is dropping the ball and the person that times it have to be the same. This so that my experiment is a fair test. And also I need to do at a room temperature, if the whether is too hot, the ball will be going faster as the ramp has some moist.

Methods

  1. Measure every cm up the side of the ramp to mark where to move it each time.
  2. Clamp the ramp to the wood.
  3. Move the ramp to the cm to want it to be.
  4. Let the ball go. Be sure not to push it.

Conclusion

        And also at 6cm, the first timing wasn’t as accurate because the three times were spread out, 1.29s, 1.41s, 135s. This is just an example.  I think this is because the person who timed this might press the start/stop button to quickly or to slower. This happens quite a lot of time.

        As I have said in my conclusion, my results does proved my prediction and support my conclusion.

        If I was to do this experiment again, I will make sure that the person who drop the ball don’t give extra push and I would have done it more than three time.

        I could extend my experiment by perhaps looking at the mass of the ball bearing – different mass to see if it affects the speed or looking at the materials of the ball bearing.

  1. The Bouncing Ball Experiment

    at the start of each experiment, and after the ball has bounced. I can then work out how much energy has been lost overall and work out how efficient the ball is. Drop Height (cm): Calculations: GPE at start (J): Bounce Height (cm): Calculations: GPE after bounce (J): 50 50

  2. Investigating the relationship between drop height and bounce height when a ball is dropped.

    You can patterns occurring and also see where mistakes were made and need to be fixed. First of all I am reasonably happy with the results except maybe a few values, but then again nothing is perfect and without mistakes, it makes your evaluation shorter.

    KE= 1/2 mv2 ,where m-mass of the object, and v-is the speed. As you let go of the trolley/car, the potential energy will convert to kinetic energy PE=KE H v2 This graph shows that the height is Proportional to the speed2 of the trolley/car.

  2. physics of the bouncing ball

    The ping-pong ball has the lowest mass closely followed by the bouncy ball. This means there will be less resistance but also less gravitational energy because the mass is less. However the bouncy ball is highly compressible and will retain vast amounts of energy upon impact.

  1. Does the height a ball is dropped from affect its efficiency?

    The floor, the ball or both become slightly dented out of shape as a result of the velocity and force they collided with. As the ball and floor try to regain their original shape, they repel each other and immediately transform the elastic potential energy they have stored into kinetic energy.

    I will repeat each measurement I take four times and take the average. To ensure the marble doesn't shatter I will take care to stop it before it rolls off the desk. To stop the whole experiment from toppling over I will take care to ensure the wood is held firmly in place in the centre.
