Question

When you view the pendulum’s swing, it shows that at the very top of the swing KE = 0. What does that tell you about the pendulum’s motion at that point?

Answer 1

At the very top of the swing the velocity=0. If the velocity is 0 then the kinetic energy is 0 as well because kinetic energy is the energy of movement.

Answer 2

Answer:

Pendulum motion at the top of swing when KE $= 0$ is nill.

Explanation:

During a swing when Kinetic energy becomes zero, potential energy reaches its peak which means all the kinetic energy of pendulum converted into the potential energy. Thus, there is no motion of pendulum at the highest point of swing. However, it gradually starts moving while coming down as the potential energy converts into kinetic energy gradually.
