    Potential and Kinetic Energy Potential and Kinetic Energy Presentation Transcript

    • Bellwork:List 6 different examples ofenergy.example: food; fire…
    • Potentialand Kinetic Energy
    • How is all energy divided? All Energy Potential Kinetic Energy EnergyGravitation Elastic Chemical Potential Potential Potential Energy Energy Energy
    • What is *Potential Energy?o *Energy that is stored and waiting to be used later
    • What is *Gravitational Potential Energy? o *Potential energy due to an object’s positionDon’t look down, o P.E. = mass x Rover! height x gravity Good boy!
    • What is *Elastic Potential Energy? o *Potential energy due compression or expansion of an elastic object.Notice the ball compressing and expanding
    • What is *Chemical Potential Energy?o *Potential energy stored within the chemical bonds of an object
    • What is *Kinetic Energy?o *Energy an object has due to its motiono K.E. = .5(mass x speed2)
    • *Kinetic Energy*Kinetic Energy increases withspeed.
    • Kinetic Energy*Kinetic Energy increases withmass.
    • Law of Conservation of Energy*The Law of Conservation ofEnergy states: *Energy is never created or destroyed *Energy is simply converted from one form to another (also called the First Law of Thermodynamics)
    • Law of Conservation of Energy
    • Your turn…List on your notes:Six examples of potential energySix examples of kinetic energyThank you for your attention today!!!
