A ball is dropped, bounces, and comes to rest.
Where did the GPE go? Can I
provide any evidence at all besides _telling_ them it
changed into thermal energy.
... the card changes color. I am not claiming all of the energy
goes to changing the color of the card,
but the collision between two surfaces
does cause a temperature change right at the impact point.
I cannot wait to set
up the demo described in the previous post of burning paper
between two colliding metal spheres.
