Conservation of Momentum
Potential energy is the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
Kinetic energy is the energy an object possess by the virtue of being in motion.
Conservation of energy
The law of conservation of energy states that energy is transferred from one form to another and cannot be created nor destroyed. For example electricity is converted into heat and light.
Potential energy examples:Batteries, Food, Gasoline, acorn hanging from a tree
Kinetic energy examples: person running, car moving,
COE examples: a person pushing someone else causing them to fall to the floor
electricity being converted into light and heat energy in a light bulb
A moving car hitting a parked car causing the parked car to move
