Potential and 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 ball at the top of a hill has potential energy because of its height.

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

How does height affect potential energy?

Back

The higher an object is, the more potential energy it has. For example, a ball on a cliff has more potential energy than a ball on the ground.

Front

What happens to potential energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, transforming potential energy into 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 mass and kinetic energy?

Back

Kinetic energy increases with mass. A heavier object moving at the same speed has more kinetic energy than a lighter object.

Front

When does an object have maximum potential energy?

Back

An object has maximum potential energy when it is at its highest point, such as at the top of a hill.

Front

When does an object have maximum kinetic energy?

Back

An object has maximum kinetic energy when it is moving at its highest speed.

Front

What is an example of potential energy?

Back

A stretched rubber band has potential energy because it is stored energy that can be released when the band is let go.

What is an example of kinetic energy?

Back

A moving car has kinetic energy because it is in motion.
