Kinetic and Potential Energy
Kinetic Energy is when energy that a body has by being in motion.
An example of Kinetic Energy is flinging a rubber band from your finger. This is Kinetic Energy because the rubber band is propelling forward, which is a form of motion.
Potential Energy is when the energy of objects are not in use yet.
An example of Potential Energy is when a rubber band is stretched and waiting to be released. This is Potential Energy because the rubber band has not yet been released so it is not in motion.
