All About Energy
Kinetic & Potential energy, & conservation of energy
Kinetic Energy and Potential Energy
When an object is in motion, it has kinetic energy. The greater the mass and speed, the more kinetic energy it has. Potential energy is the energy that an object holds while it is at rest. Potential energy is stored and the more potential energy an object has, the more kinetic energy it will have when it is put in motion.
Potential Energy
As you can see, the ball is at rest. It has stored energy
Kinetic energy
As you can see, the ball is rolling down the hill.
Conservation of Energy
Conservation of Energy
The law of conservation of energy is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another.
