8th Grade_ Potential Energy

Front

What type of energy is stored in a bungee cord when it is stretched?

Back

Elastic potential energy.

Front

What is the definition of potential energy?

Back

Stored energy that results from the position or shape of an object.

Front

When you compress a spring, what type of energy are you storing?

Back

Elastic energy.

Front

What happens to the elastic potential energy of a spring when it is compressed?

Back

It increases.

Front

What happens to the potential energy of a roller coaster as it is pulled to the top of a hill?

Back

The potential energy increases as it gains height.

Front

What is the formula for gravitational potential energy?

Back

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

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position or shape.

Front

How does height affect potential energy?

Back

Potential energy increases with height.

Front

What is an example of elastic potential energy in everyday life?

Back

A stretched rubber band or a compressed spring.

Front

What factors affect the amount of potential energy an object has?

Back

Mass, height, and the type of energy (gravitational or elastic).
