A pendulum is pulled back from it equilibrium (center) position and released.?

Question

a. What form of energy is added to the system before it is released? Explain.

b. At what points in the motion of the pendulum after release is its kinetic energy the greatest? Explain.

c. At what points is the potential energy the greatest? Explain.

Answer 1

Moon is correct.

The explanations are:

A. The energy is potential as it has not been put in motion.

B. The motion is the greatest when it is straight down because once it starts to swing up, gravity is exerting its pull on the pendulum, causing it to slow down.

C. Referring to A, the potential is the greatest before it is released (before gravity, air resistance etc begin to affect it).

Answer 2

A. Potential B.At the middle C.Before it is dropped.         There are your homework answers.
