Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is stored energy or energy due to an object's position.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is the formula for gravitational potential energy?

Back

Gravitational potential energy (GPE) = mass (m) × gravity (g) × height (h).

Front

What does the law of conservation of energy state?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

How does potential energy convert to kinetic energy?

Back

Potential energy converts to kinetic energy when an object moves from a higher position to a lower position.

Front

What is an example of potential energy?

Back

A rock held at the top of a hill has potential energy due to its position.

Front

What is an example of kinetic energy?

Back

A rolling ball has kinetic energy due to its motion.

Front

What happens to kinetic energy as speed increases?

Back

Kinetic energy increases as the speed of an object increases.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with the mass of the object; it is directly proportional.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).
