  1. i see you put 2 cubes of energy into the air but their really should be a little more because theirs actually at least 2 types of energy that is caused with the ball going into the air. theirs at least thermal energy and friction between the ground and the air.

    1. So if you think there should be more than 2 cubes, do you think an equal amount of cubes would be in the ball?

  2. I noticed that your drawing of the bubbles didn't make sense. Is the ball coming off the ground or falling from your hand?

  3. Joanna - what type of energy stayed in the hand?

  4. wouldn't the ball bounce back up?

    1. That wasn't the situation just the ball hitting the ground, not bouncing back up. Cameron "See Ya in 1st" Bunger. P6

  5. while the ball is bouncing it would not potential, it would be kinetic

    1. At what points do you think the ball has potential energy?

  6. How does an object always have potential energy if it's not moving. Potential is stored, kinetic is moving. The ball is moving so it's kinetic.

    1. Do you think it is possible for an object to have BOTH kinetic and potential energies at the same time? Can you think of an example where this might be the case?

  7. I noticed you didnt include the bubble of the hand dropping the ball . Why is that ?

  8. The mechanical doesn't just go into the ground, it goes into the ground, then the energy rebounds back into the ball making it soar.

  9. There wasn't a lot of explanation of how mechanical energy transformed into other forms of energy (Sound, Thermal, etc.). Also I'm assuming that the mechanical energy came from something else, such as potential gravitational or other mechanical energy, but can you clarify that point? Poster 2 made a good point.

  10. The drawing of the bubbles and the arrows were confusing

  11. Wouldn't the ball bounce back up leading to more energy transfers and transformation you did not explain? What surface is the ball being dropped onto, because that can play a roll in energy transformation and transfers?

  12. When the ball is bouncing, wouldnt the energy transfer from potential gravitational to kinetic mechanical?

    ReplyDelete
  13. I thought your video demonstration was pretty clear, my group picked the same scenario. Did you consider there might be some other energy transfers when the ball drops to the ground?

  14. There shouldn't be any potential energy left in the ball.

  16. do you have that many cubes on purpose?

  17. really good experiment but think there should be more cubes in the air.

  19. Hey,
    How is it kinetic when the ball is moving? And also, shouldn't there be gravitational energy when the ball falls from your hand?

    1. The ball moving had mechanical kinetic enegry because mechanical energy is when something moves from one place to another.

    2. I though it was well done. The energy distribution was well done considering the factors. Cameron Bunger. P6
