If the total mechanical energy of the system is 100 J: Where does the pendulum have 100 J of kinetic energy? Where does the pendulum have 100 J of potential energy? (Label both points.)Where does the pendulum have 50 J of potential energy? (Label both

Explanation:

A simple pendulum consists of a string to which a bulb is attached and the string is tied to a support. The string swings from one end to the other as shown.

At the both ends, the energy of the pendulum is all potential. Hence we have 100J potential energy at both ends.

When the pendulum is in motion, the energy is all kinetic at the center of motion. Hence at that point, we have 100J kinetic energy.

In between both extremes the energy is both kinetic and potential as shown. The total energy is this a summation of the two.
