  1. why did you use kinetic energy for when its falling?

    1. What kind of energy do you think it should be while falling?

  2. thr ball falls from your hand because you made it fall not because of the air ... the air is the middle of both the hand and the ground .

  3. how does the air have potential to know the ball out of your hand when there isn't and wind to make it fall unless you move your hand.

  4. Good job on speaking clearly, but I agree as before that the air does not contain any pontentail energy "to knock the ball out of your hand," the ball falls as a result of you dropping the ball and gravatational potentail energy.

    1. Is it possible that the air has potential energy that doesn't particularly matter to this scenario?

  5. How does the ball have the potential to knock the ball out of your hand? How come you guys didnt use any kenetic or sound energy in the ball or air? - Kaylee P.3

  6. The ball would need mechanical energy as it falls because it is moving.

    Good job on describing what activity you did. We forgot to do that:). When you said there was potential energy in the ball for it to fall, you should be more exact and say what kind of potential energy.

  8. Another improvemnet you could make would be to possibly include sound energy in your diagram. Shooting in a quieter place would help also.

  9. loved the beginning and ending of the video... But the explanations of the energy transers were kind of confusing...

  10. You said the ball was potential energy and the air was potential energy. Wasn't potential energy only supposed to be in one spot?
