Correct Answer

Explanation

Pendulum in motion

1 pts

 

The pendulum shown here is just about to hit the show.  When it was at position A, it had (1) energy.  Just before it hits the shoe, it has fallen to the level of the shoe and has thus lost its (2) energy.  So how can it move the shoe if it has no (3) energy anymore?  The answer is that the pendulum still has energy, but now the energy is due to its (4) rather than to its (5).
