Kinetic and Potential Energy Review

Front

What is velocity?

Back

Velocity is the same as speed, but it includes direction.

Front

What type of energy is caused by motion?

Back

Kinetic energy is the energy caused by motion.

Front

What determines the amount of kinetic energy in an object?

Back

The amount of kinetic energy is determined by its speed and mass.

Front

If a car has KE = 0 and PE = 100, what can we say about its energy?

Back

The car has no kinetic energy and all its energy is potential.

Front

When you do work, what are you exerting?

Back

When you do work, you are exerting energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

Give an example of kinetic energy in everyday life.

Back

A moving car, a running dog, or a thrown ball are examples of kinetic energy.

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.

Front

What is the relationship between height and potential energy?

Back

The higher an object is, the more potential energy it has due to gravity.

Front

What happens to kinetic energy when speed increases?

Back

Kinetic energy increases as speed increases, since it is proportional to the square of the speed.
