Potential and kinetic energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball at the top of a hill has potential energy.

Front

How does speed affect kinetic energy?

Back

Increasing an object's speed will increase its kinetic energy.

Front

What is the relationship between mass and kinetic energy?

Back

The more mass an object has, the more kinetic energy it has when moving at the same speed.

Front

Which has more kinetic energy: a moving car or a moving bicycle?

Back

A moving car has more kinetic energy than a moving bicycle because it has more mass.

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 an example of an object with kinetic energy?

Back

A rolling tennis ball is an example of an object with kinetic energy.

Front

What is an example of an object with potential energy?

Back

A car parked at the top of a hill is an example of an object with potential energy.

Front

Where is kinetic energy greatest in a roller coaster?

Back

Kinetic energy is greatest at the lowest point of the roller coaster.

Front

What is the formula for kinetic energy?

Back

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