DESCRIPTION

2 Forms of Energy –Kinetic and Potential. Kinetic energy. Kinetic energy is movement energy This is energy that is being used for movement right now. Potential energy. Potential energy is stored energy. This is energy that could be used in the future, but isn’t being used right now. - PowerPoint PPT Presentation

2 Forms of Energy –Kinetic and Potential

Page 2: 2 Forms of Energy –Kinetic and Potential

Kinetic energy• Kinetic energy is

movement energy• This is energy that is

being used for movement right now.

• KE = mv

Page 3: 2 Forms of Energy –Kinetic and Potential

Potential energy• Potential energy is

stored energy.• This is energy that could

be used in the future, but isn’t being used right now.

• PE = mgh

Page 4: 2 Forms of Energy –Kinetic and Potential

Potential and kinetic• Most different types of

energy can be classified as either kinetic energy, potential energy, or both.

The sum of the kinetic and potential energy is called mechanical energy

Page 5: 2 Forms of Energy –Kinetic and Potential

Potential and kinetic• Potential energy can

turn into kinetic energy, and kinetic energy can turn into potential energy.

• This means that kinetic and potential energy are cyclic.
