d. What happens to potential energy as kinetic energy increases?
____________________________________
a. The gravitational potential energy is highest when the object is at its highest point or furthest from the Earth's surface. It is lowest when the object is at its lowest point or closest to the Earth's surface.
b. The kinetic energy is highest when the object is at its fastest speed. It is lowest when the object is at rest or moving at a slow speed.
c. The kinetic and gravitational potential energy levels are the same when the object is at its midpoint or halfway between its highest and lowest point.
d. As kinetic energy increases, potential energy decreases. This is because potential energy is converted into kinetic energy as an object speeds up or falls towards the Earth's surface.
