Document Summary
Episode 13 and 14 / conservation of energy, potential energy / Energy is always conserved no matter what occurs, this is a fundamental law of physics. There are three notable conservation laws, the conservation of energy, momentum and angular momentum. These three quantities cannot be created nor destroyed so the amounts of them are constant throughout the universe and have been forever. Work, a quantification of energy, is equal to force times height. Near the surface of the earth force can be substituted by mass time gravity. Potential energy, designated as u can be written as u=mgh, so the potential energy of an object is exactly the same as the work applied to it. Galileo would roll a ball down an inclined plane and then up a similar one. He noted that the ball would always return to its original height, regardless of the shape of the other inclined plane, demonstrating some form of conservation.
