Potential vs. Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a rock at the top of a hill has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

How does mass affect energy?

Back

The amount of material (mass) in an object affects its energy. More mass means more potential and kinetic energy.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, assuming no energy is lost to air resistance.

Front

What is the relationship between kinetic energy and mass?

Back

The relationship between kinetic energy and mass is linear; as mass increases, kinetic energy increases if speed remains constant.

Front

What is an example of potential energy?

Back

A drawn bow has potential energy because the energy is stored in the bent bow.

Front

What is an example of kinetic energy?

Back

A moving car has kinetic energy because it is in motion.

Front

What are indicators that an object has energy?

Back

Light, sound, heat, and motion are indicators that an object has energy.

Front

Where is kinetic energy greatest on a roller coaster?

Back

Kinetic energy is greatest at the bottom of the highest hill on a roller coaster.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.
