Question

examine the model of the car on the road. if the car stops at each of the places on the road, where is potential energy the lowest? a point a b point b c point c d they are all the same

Explanation:

Step1: Recall 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.

Step2: Compare heights at points

The mass $m$ and $g$ are constant. The lower the height $h$, the lower the potential energy. Point B has the lowest height among points A, B, and C.

Answer:

B. point B
