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.

Question

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
Potential energy is destroyed during a roller coaster ride.
d
Kinetic energy is created during a roller coaster ride.

Answer 1

The correct conclusion based on the investigation of energy transfer between potential and kinetic energy on a roller coaster is:

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

This reflects the principle of conservation of energy, where energy can convert from one form to another (from potential to kinetic and vice versa), but the total energy of the system remains constant.
