Kinetic and Potential Energy Review

Front

What is potential energy?

Back

Potential energy is stored energy that has the potential to do work. It is energy based on an object's position or condition.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

Which has more potential energy: a boulder on a cliff or a boulder on the ground?

Back

A boulder on a cliff has more potential energy because it is at a higher position.

Front

What is energy transformation?

Back

Energy transformation is the process of changing one form of energy into another form of energy.

Front

What is energy transfer?

Back

Energy transfer is the movement of energy from one object to another.

Front

Give an example of kinetic energy.

Back

A moving car is an example of kinetic energy.

Front

Give an example of potential energy.

Back

A stretched rubber band is an example of potential energy.

Front

At which point in a roller coaster is potential energy the greatest?

Back

Potential energy is greatest at the highest point of the roller coaster.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the formula for kinetic energy?

Back

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