Kinetic and Potential Energy

Front

What is the definition of energy?

Back

Energy is the ability to do work or cause change.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state.

Front

What is the Law of Conservation of Energy?

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 mass affect kinetic energy?

Back

Kinetic energy increases with mass; the more mass an object has, the more kinetic energy it has at the same speed.

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 gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height above the ground.

Front

How does height affect potential energy?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car, a running athlete, or a flowing river are examples of kinetic energy.

Front

What is an example of potential energy in everyday life?

Back

A drawn bow, a rock at the top of a hill, or water stored in a dam are examples of potential energy.
