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 stored energy that has the potential to do work. It is energy that is held in readiness.

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 kinetic energy?

Back

An example of kinetic energy is a roller coaster speeding down a hill.

Front

What is an example of potential energy?

Back

An example of potential energy is the pulled back string on an archer's bow.

Front

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

Back

Potential energy is greatest at the highest point of the roller coaster.

Front

What type of energy is in a stretched rubber band?

Back

A stretched rubber band contains potential energy.

Front

How does mass affect kinetic energy?

Back

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

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.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.
