where is the potential energy of the roller coaster the lowest? a a b b c c d d
where is the potential energy of the roller coaster the lowest? a a b b c c d d
Answer
Answer:
D. D
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: Analyze height at each point
At point D, the height $h$ of the roller - coaster is the lowest among points A, B, C, and D. Since $m$ and $g$ are constant, when $h$ is the smallest, the potential energy $U$ is the smallest.
