Question

a child swings on a swing at the playground. the motion of the swing resembles the motion of a pendulum. when is the kinetic energy of the swing increasing? it has the same amount of kinetic energy the entire time as it swings down toward the bottom at the bottom of the swing when it reaches the highest point going forward or backward

Explanation:

The swing's motion is like a pendulum. Kinetic energy \(KE=\frac{1}{2}mv^{2}\) (where \(m\) is mass and \(v\) is velocity). As the swing moves down, gravitational potential energy \(PE = mgh\) (where \(h\) is height) converts to kinetic energy. At the bottom, \(KE\) is maximum. At the highest points, \(v = 0\), so \(KE=0\). The \(KE\) is not constant.

Answer:

as it swings down toward the bottom
