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 based on an object's position or state.

Front

What factors affect Gravitational Potential Energy?

Back

Gravitational potential energy depends on the height and mass of an object.

Front

Give an example of Kinetic Energy.

Back

A tennis ball rolling across the court is an example of kinetic energy.

Front

Give an example of Potential Energy.

Back

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

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 formula for Potential Energy?

Back

The formula for gravitational potential energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How does height affect Potential Energy?

Back

The higher an object is, the more potential energy it has because it has the potential to fall.

Front

How does mass affect Potential Energy?

Back

The more mass an object has, the more potential energy it has at a given height.

Front

What happens to Kinetic Energy when an object slows down?

Back

When an object slows down, its kinetic energy decreases.
