Question

A student is investigating the transfer of energy between potential and kinetic. The student observes a roller coaster at four locations on the track and creates a graph based on her observations.

What conclusion can be made based on the graph?
A.Kinetic and potential energy change, but total energy stays the same.
B.Potential energy is increased, but kinetic energy stays the same.
C.Kinetic energy is created during a roller coaster ride.
D.Potential energy is destroyed during a roller coaster ride.

Answer 1

Kinetic and potential energy change, but total energy stays the same.

Answer 2

A. Kinetic and potential energy change, but total energy remains the same.
