Question

where does the pendulum have its maximum kinetic energy?
at the bottom of the swing
at the top of the swing
in between the top and the bottom of the swing
rewatch

Explanation:

Kinetic energy (KE) is related to motion, \( KE=\frac{1}{2}mv^{2} \). At the top of the pendulum's swing, it momentarily stops, so velocity \( v = 0 \), meaning KE is minimum (maximum potential energy here). At the bottom of the swing, the pendulum's speed is maximum (as potential energy is converted to kinetic energy). So maximum KE occurs at the bottom.

Answer:

A. At the bottom of the swing
