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 ball held at a height has potential energy because of its position above the ground.

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 are indicators of energy in an object?

Back

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

Front

Which has more potential energy: a ball at 3 meters or a ball at 1 meter?

Back

A ball held at 3 meters has more potential energy than a ball at 1 meter.

Front

What happens to kinetic energy if the speed of an object doubles?

Back

If the speed of an object doubles, its kinetic energy quadruples.

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 proportionally.

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is the formula for calculating potential energy?

Back

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

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy due to its position and tension.
