Question

6
this graph shows different points on the path of a ball rolling down and then up a hill. order the points from greatest to least potential energy.

Explanation:

Step1: Recall potential energy formula

The gravitational - potential energy formula is $U = mgh$, where $m$ is the mass, $g$ is the acceleration due to gravity, and $h$ is the height. Assuming the mass of the ball and $g$ are constant, the potential energy depends only on the height $h$.

Step2: Identify heights of each point

Point A is at a height of 10 m, point G is also at a height of 10 m, point B is at a height greater than 5 m but less than 10 m, point F is at a height greater than 5 m but less than 10 m, point C is at a height of 5 m, point E is at a height of 5 m, and point D is at a height of 0 m.

Step3: Order the points by height

The order of the points from greatest to least height (and thus from greatest to least potential energy) is A = G > B = F > C = E > D.

Answer:

A = G > B = F > C = E > D
