What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, water stored behind a dam has potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. For example, a moving skateboard or a strummed guitar has kinetic energy.

What type of energy is being used when a ball is thrown?

Back

Kinetic energy.

Front

What type of energy does an acorn hanging from a tree have?

Back

Potential energy.

Front

What happens to potential energy when an object falls?

Back

It is converted into kinetic energy as the object moves downward.

Front

Can an object have both potential and kinetic energy at the same time?

Back

Yes, an object can have both types of energy. For example, a roller coaster at the top of a hill has potential energy, and as it descends, it gains kinetic energy.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
