|
low PE and high KE
|
|
|
high PE and low KE
|
|
|
low PE and low KE
|
|
|
high PE and high KE
|
Explanation:
Detailed explanation-1: -At the highest point on the roller coaster (assuming it has no velocity), the object has a maximum quantity of gravitational potential energy and no kinetic energy. As the object begins moving down to the bottom, its gravitational potential energy begins to decrease and the kinetic energy begins to increase.
Detailed explanation-2: -Kinetic energy is greatest at the lowest point of a roller coaster and least at the highest point.
