in a mechanical clock, the swinging of a pendulum causes the hands to move. the diagram shows the path of the pendulum as it swings. at which point in its swing does the pendulum have the least gravitational potential energy?\npoint a\npoint b\npoint c\npoint d\ndone

Answer

Explanation:

Step1: Recall gravitational - potential - energy formula

The gravitational potential energy formula is $U = mgh$, where $m$ is mass, $g$ is the acceleration due to gravity, and $h$ is the height above a reference level.

Step2: Analyze the height of the pendulum at different points

The lower the height $h$ of the pendulum bob, the less gravitational potential energy it has. Among points A, B, C, and D, point C is the lowest point in the pendulum's swing.

Answer:

C. point C
