  1. I noticed that you said thermal energy is on the floor. How is there thermal energy on the floor?

    i dont think mechanical energy goes into the floor... and i noticed you said the sound hits the floor. the sound wont hit the floor it would be traveling through the air. and when you said the thermal energy is on the ground its actully moving through the air as the ball hits the ground.

    1. So, if you are thinking mechanical energy does not go into the floor, where does it go when the ball is still (not moving) on the floor?

  3. I dont think that the mechanical energy goes to the floor and same with the sound. Actually, the sound energy would be in the air. Same goes for the thermal energy.

  4. I noticed you said your names& showed your faces ? Also you didnt include that the hand is dropping the ball . And isnt their potential enery in the ball ? And gravitational when the ball is off the ground ? Did you guys consider these ?

  5. I don't really understand this whole concept, but I could see that you did a decent good job describing how the energy transfers between objects. It was kind of hard to understand though because you were a little vague describing what you did.

  6. Does the ball start with potential gravitational energy?

  7. Someone is going to stalk you... You took too long introducing everyone and took to little explaining things. I could barely hear you and you really only just said what everything did and not why. Careful you don't drop anymore cubes ;)

  8. I hear my bff Saaaakkkkara. Why is the floor getting hotter?

    1. Friction can create heat. Another question though...is the "heat" (thermal energy) in the floor, the ball, the air, or some combination of all three?

    1. Was there any potential energy in the ball

  11. was there a reason that you guys only used 5 cubes and picked that senerio?

  13. Really didn't like the intro, but anyways, shouldn't there be Gravitational Energy from when the ball falls from your hand ?

  14. I see you're point on how the thermal energy transfers into the ground, but what about the potential energy that Josh mentioned in the comments? Shouldn't that be explained in an energy transformation? And also what about the other forces enacting on the ball? Can you explain more on the topic of the potential energy?
