Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
On a roller coaster, where is maximum potential energy?
A
At the bottom of a big hill
B
When going around a corner
C
When going upside down
D
At the top of a big hill
Explanation: 

Detailed explanation-1: -Gravitational potential energy is greatest at the highest point of a roller coaster and least at the lowest point.

Detailed explanation-2: -The potential energy of the roller coaster when it is at the top of a hill is converted into kinetic energy as the roller coaster speeds down the hill. As the roller coaster goes up another hill, it slows down. The kinetic energy is converted into potential energy.

Detailed explanation-3: -When you (or a rock) are standing at the top of a hill, you possess more potential energy than when standing at the bottom. This is because your position relative to the Earth’s center of gravity can exert potential energy upon you to bring you closer to that center.

Detailed explanation-4: -Being at the top of a hill, the object contains only potential energy, as there’s a height difference between the top of a hill and the ground level. Since we are assuming no motion at this point, there is no kinetic energy present.

Detailed explanation-5: -The man’s mass and the acceleration of gravity will remain constant. The only changing variable is height. When the height is greatest, the potential energy will be the greatest. We can conclude that the potential energy will thus be greatest at the top of the hill.
