Unit 2.2 Force&Motion: Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

What is an example of potential energy?

Back

A stretched rubber band is an example of potential energy because it has the potential to do work when released.

Front

What type of energy is associated with motion?

Back

Mechanical energy is the type of energy associated with the motion of an object.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object that is used to do work.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground.

Front

What is an example of gravitational potential energy?

Back

A book on a shelf has gravitational potential energy because of its height above the ground.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the particle motion is perpendicular to the direction of wave motion.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave where the particle motion is parallel to the direction of wave motion.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves do not require a medium.

Front

What is an example of a mechanical wave?

Back

Sound waves are an example of mechanical waves because they require a medium (like air) to travel.
