Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass of the object and its velocity.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

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 formula for Potential Energy?

Back

The formula for Gravitational Potential Energy (PE) 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

What happens to Kinetic Energy when an object speeds up?

Back

When an object speeds up, its Kinetic Energy increases because it is moving faster.

Front

What is an example of Potential Energy?

Back

A compressed spring or a stretched rubber band are examples of Potential Energy.

Front

What is an example of Kinetic Energy?

Back

A moving car or a rolling ball are examples of Kinetic Energy.

Front

How can you increase Kinetic Energy?

Back

You can increase Kinetic Energy by moving faster or increasing the mass of the object.

Front

What type of energy is greatest at the highest point of a roller coaster?

Back

At the highest point, Potential Energy is greatest because the roller coaster has the potential to fall.
