Which statement is a true comparison of potential and kinetic energy?
Both potential and kinetic energy are exhibited when an object is moving across the ground.
Kinetic and potential energy are alike in that neither one can be created nor destroyed.
Kinetic and potential energy are different because potential energy can be created, and kinetic energy is created from potential energy.
Kinetic and potential energy cannot be transformed, or changed, from one to the other.
What happens to the potential energy of an object as it falls?
Potential energy increases.
Potential energy is destroyed.
Potential energy transforms to kinetic energy.
None of the above
