Potential Energy and Kinetic Energy

Front

What is Potential Energy?

Back

The stored energy of an object due to its position or condition.

Front

What is Kinetic Energy?

Back

The energy an object has due to its motion.

Front

At which point is potential energy greatest on a roller coaster?

Back

At the top of a big hill.

Front

What does kinetic energy depend on?

Back

The mass and speed of an object.

Front

Which of the following is an example of kinetic energy?

Back

Sound.

Front

Where is potential energy greatest in a gravitational field?

Back

At the highest point in the field.

Front

What happens to potential energy as an object falls?

Back

It decreases as kinetic energy increases.

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height.

Front

Can an object have both potential and kinetic energy at the same time?

Back

Yes, for example, a roller coaster at the top of a hill is a good example.
