Question

drag the answer in order from most potential energy (at the top) to least potential energy (at the bottom)
source
target
position a on the roller coaster
position b on the roller coaster
position d on the roller coaster
a person in an airplane in the sky
position c on the roller coaster
a person standing on the ground

Explanation:

Gravitational potential energy is given by $U = mgh$ (where $m$ is mass, $g$ is acceleration due to gravity, and $h$ is height). Higher the height above the ground - level, greater the potential energy. Assuming similar masses for all cases, the person in the airplane is at the greatest height, followed by positions on the roller - coaster based on their height above the ground, and the person on the ground has the least potential energy.

Answer:

1. A person in an airplane in the sky
2. Position A on the roller coaster (assuming it is one of the higher positions)
3. Position B on the roller coaster
4. Position D on the roller coaster
5. Position C on the roller coaster
6. A person standing on the ground
