Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is 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 calculating Kinetic Energy?

Back

KE = 1/2 mv², where KE is kinetic energy, m is mass, and v is velocity.

Front

What is the formula for calculating Potential Energy?

Back

PE = mgh, where PE is potential energy, m is mass, g is acceleration due to gravity, and h is height.

Front

What is an example of Kinetic Energy?

Back

A tennis ball rolling across the court.

Front

What is an example of Potential Energy?

Back

A compressed spring or water stored in a dam.

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 due to its greater mass and speed.

Front

What type of energy can chemical energy transform into?

Back

Chemical energy can transform into heat, light, and electrical energy.

Front

What is NOT an example of Potential Energy?

Back

A ball traveling at 10 m/s is not an example of potential energy; it is kinetic energy.

Front

How do you calculate the Kinetic Energy of a cheetah running at 31.0 m/s with a mass of 47.0 kg?

Back

KE = 1/2 mv² = 1/2 * 47.0 kg * (31.0 m/s)² = 22,584 Joules.
