- 5. Multiple Choice
A 20-kg ball and a 50-kg ball rest at the top of a ramp. Which statement best describes the potential energy of the balls?
The 20-kg ball has the greater potential energy because it has less inertia.
They have the same potential energy because their positions are the same.
The 50-kg ball has the greater potential energy because it has the greater mass.
They have the same potential energy because gravity has the same effect on each one.

- 14. Multiple Choice
What is the difference between potential energy and kinetic energy?
Potential energy is the energy of an object due to its motion, while kinetic energy is energy due to its position.
Potential energy is the energy of an object due to an applied force, while kinetic energy is energy stored after the applied force.
Potential energy is the energy stored after an applied force, while kinetic energy is the energy used from the applied force.
Potential energy is the energy of an object due to its position, while kinetic energy is energy due to its motion.
