Question

energy of motion unit test
a child is swinging back and forth on a swing. changes in her kinetic and potential energy are happening each moment. at which point, or multiple points, in her swinging would each of these two types of energy be at a maximum? in one to two sentences, describe these points and which type of energy is at a maximum at each point. (2 points)

short answer rubric (2 points)

Explanation:

When the child is at the lowest point of the swing, her kinetic energy is at a maximum because her speed is highest there. When she is at the highest points (the extremes of her swing), her potential energy is at a maximum due to her greatest height.

Answer:

At the lowest point of the swing, kinetic energy is at a maximum. At the highest points (the two extreme ends of the swing), potential energy is at a maximum.
