Kinetic and Potential Energy

What is Potential Energy?

Real-lifeExample:

When I go to the Dells this summer, I am going to ride the "Scorpions Tail" at Noah's Ark. At the start of the ride, my GPE will be 45kg * 33m * 9.8m/s/s or 14553 joules. When I am going down the slide, I know my Kinetic Energy must be less then or equal to 14553. If I know my KE is 14,553 and my mass is 45kg, I can find my velocity! I would use the formula 14553 = .5 * 45kg * V^2 to find out that my velocity on the ride was 25.5 m/s!

Potential Energy is Energy that is waiting to happen. If a box is at the top of a building, and it isn't falling, it has the POTENTIAL to fall, therefore it has potential energy.

KE and PE are types of energy, measured in Joules. The GPE is the greatest amount of potential energy that can be found in the specific instance. This occurs at the beginning. The KE and the PE combined can never be greater then the GPE. To find KE and PE, the formulas KE = .5 * M * V^2 and PE = M * H * G can be used.

When something has potential Energy, it is measured in Joules. When the Potential Energy is converted to Kinetic Energy, the KE never exceeds the original PE.

What is Kinetic Energy?

Kinetic Energy is the Energy of motion. If that box falls off the building, it will have Kinetic energy.

PE = M * H * GKE = .5 * M * V^2
