Question

1. The mechanical energy of the pendulum at the highest point equals

a. kinetic energy only.
b. kinetic energy x potential energy.
c. potential energy only.
d. zero.

Answer 1

c. potential energy only

Step-by-step explanation:

at highest point the body will having some height and gravitational force will work on it.

since the velocity at highest point will be zero therefore there will no kinetic energy
