**Kinetic**Energy Potential Energy Elastic Potential Energy Gravitation Potential Energy Chemical Potential Energy How is all energy divided? All Energy**What is Potential Energy?**• Energy that is stored and waiting to be used later**What is Gravitational Potential Energy?**• Potential energy due to an object’s position • P.E. = mass x height x gravity Don’t look down, Rover! Good boy!**What is Elastic Potential Energy?**• Potential energy due compression or expansion of an elastic object. Notice the ball compressing and expanding**What is Chemical Potential Energy?**• Potential energy stored within the chemical bonds of an object**What is Kinetic Energy?**• Energy an object has due to its motion • K.E. = 1/2mv2**Kinetic Energy Depends on 2 factors**If Dino and the car have the same velocity, which has the greater KE? If the trucks have the same mass, which one has greater KE? Mass and Velocity**Which factor has the greater impact on KE?**Velocity has greater influence because it is SQUARED in the formula!! Think about the formula!!**The total amt of energy remains constant!!**KE i + PE i = KE f + PE f**Mechanical Energy**The total amount of KE and PE is referred to as the total MECHANICAL ENERGY of an object. TME = KE + PE
