Question 6

A roller coaster is halfway down a slope. Which of the following is true about potential and kinetic energy?

Accepted Answer

as the kinetic energy increases, the potential energy decreases.

Answer

the amount of potential energy decreases, but the amount of kinetic energy does not change.

Answer

the amount of kinetic energy is equal to one-half of the potential energy.

Answer

as the potential energy decreases, the kinetic energy decreases.
