Cliff Notes

I.   Energy: how much work something
               -measured in joules, J
II.    Potential Energy
    A.     Potential energy: energy of position
    B.     Depends on: mass, height
    C.     Formula: PE = mgh
    D. Examples
            Ex1 If your egg drop device has a mass of 2 kg, how much potential energy does it hold at a height of 10 meters? 196 J
III.   Kinetic Energy
    A.   Kinetic energy: energy of motion
    B.  Depends on: mass, velocity
    C.    Formula: KE = ½mv^{2
    D.     Examples
                Ex2 The bird has a mass of 2 kg.  It is flying at a speed of 5 m/s.  Find its kinetic energy. 25 J}
