A plasticine ball falls to the ground and stays there.
How is energy transformed here?
Compare the states "falling ball" and "lying ball" using the particle model:
How are the particles moving respectively?
When the ball hits the ground, kinetic energy is transformed into heat.
Kinetic energy was connected with joint down-movement of all particles.
Now heat means chaotic movement of the particles in all directions..
view of the gigantic number of particles it is virtually impossible
that all of them should happen to move in one direction (up) again,
which would be necessary for the ball jumping up again. The Energy is
is not consumed in the sense of "annihilated". It is transformed into
energy forms which cannot be used again without further measure.
