Energy Notes

Energy- Is the ability to do work Has 2 states Potential energy that is stored due to position or shape TWO different forms gravitational potential energy depends on: mass height gravity formula: PE= mgh, unit= J (Joul: named after James Prescott Joul) Elastic Potential Energy potential energy of an object stretched or compressed. Kinetic Energy that is found in a moving object Depends on: Mass Speed Formula: KE=½ mv2 PE and KE ENERGY CONVERSIONS- The gravitational potential energy of an object is converted to the kinetic energy of motion as an object falls.
