Potential & Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a stretched rubber band has potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What factors affect kinetic energy?

Back

Kinetic energy is affected by an object's mass and speed. The formula is KE = 1/2 mv², where m is mass and v is speed.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy.

Front

What type of energy does an apple rolling on a table have?

Back

An apple rolling on a table has kinetic energy.

Front

If an object is at rest, what type of energy does it have?

Back

An object at rest has potential energy, but no kinetic energy.

Front

How does speed affect kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What happens to potential energy when an object falls?

Back

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

Front

Which has more kinetic energy: a car driving down a hill or a person running down a hill?

Back

A car driving down a hill has more kinetic energy than a person running down a hill.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with an increase in mass, assuming speed remains constant.
