Unit 4: Energy Review

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What happens to elastic potential energy when a spring is released?

Back

When a spring is released, the elastic potential energy is converted into kinetic energy.

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is the unit of energy?

Back

The unit of energy is Joules (J).

Front

What type of energy is associated with motion?

Back

Kinetic energy is the type of energy associated with motion.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field.

Front

How is energy transformed from one form to another?

Back

Energy transformation occurs when energy changes from one form to another, such as from potential energy to kinetic energy.

Front

What is sound energy?

Back

Sound energy is a form of kinetic energy that is produced by vibrating objects and transmitted through a medium.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by a factor of four.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car or a rolling ball are examples of kinetic energy in everyday life.
