# Kinetic vs. potential

## Kinetic energy

* Something that is moving not staying still it has to be moving to be kinetic energy. * Kinetic energy is the energy that is always moving potential is always staying put. * Ex.) moving roller coaster, a closing door.

## Potential energy

Potential energy is when the object is at a complete stop. It is the complete opposite of kinetic energy kinetic energy is the moving energy. Potential energy is not moving. Ex.) roller coaster at the top not moving,the fridge is another example.

## Kinetic energy

Kinetic energy is energy of motion. The kinetic energy of an object is the energy it possesses because of its motion. The kinetic energy* of a pointmass m is given by

## Potential energy

Potential energy is energy which results from position or configuration. An object may have the capacity for doing work as a result of its position in a gravitational field (gravitational potential energy), an electric field (electric potential energy), or a magnetic field (magnetic potential energy). It may haveelastic potential energy as a result of a stretched spring or other elastic deformation.

## Kinetic and potential

Kinetic Energy

Kinetic Energy is energy that is in motion. Moving water and wind are good examples of kinetic energy. Electricity is also kinetic energy because even though you can't see it happen, electricity involves electrons moving in conductors.

Potential Energy

Energy is measured in the amount of "work" it does. Potential Energyis stored energy. Examples of potential energy are oil sitting in a barrel, or water in a lake in the mountains. This energy is referred to as potential energy, because if it were released, it would do a lot of work.

Energy can change from one form to another. A good example is a Roller Coaster. When it is on its way up, it is using kinetic energy since the energy is in motion. When it reaches the top it has potential (or stored) energy. When it goes down the hill it is using kinetic energy again.

Other Types of Energy

There are other types of energy as well:
