0708 potential and_kinetic-1 0708 potential and_kinetic-1 Presentation Transcript

  • Potential and Kinetic Energy
  • How is all energy divided? All Energy Potential Energy Kinetic Energy Gravitation Potential Energy Elastic Potential Energy Chemical Potential 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. = .5(mass x speed 2 )
