How do kinetic and potential energy differ?

• Kinetic energy is stored energy, while potential energy is energy of motion.

• Kinetic energy is energy of motion, while potential energy is stored energy.

• Both are forms of energy that cannot be transformed.

• Both are forms of energy that are always equal.

Which of the following is an example of energy transformation?

• A book resting on a table

• A car engine converting fuel into motion

• A stationary bicycle

• A rock sitting at the top of a hill
