Loss of Energy Mechanical energy is the sum of the energy of motion:
{"Image DocumentName": "Loss of Energy Mechanical energy is the sum of the energy of motion:", "Image ImageDescription": "KE (Kinetic Energy) = \u00bd mv2. GPE (Gravitational Potential Energy) = mpg. where m = mass, v = velocity (speed), g = gravitational pull, and p = potential energy. The total energy in a system is conserved, but when a ball bounces, it loses mechanical energy because the collision between the ball and the surface is inelastic. The amount of energy that the ball loses will depend on the coefficient of restitution, a ration of its pre-collision velocity to its post-collision velocity.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
