    • AP Physics 1: Work and Energy 7: Conservative Force and Potential Energy
    • AP Physics 1: Work and Energy 8: Conservation of Energy: Tarzan Swinging on Vine Problem
    • AP Physics 1: Work and Energy 9: Conservation of Energy: Frictionless Track Problem
        • Whether it is an object released from rest into free fall, Tazan grabbing onto a vine, starting from rest, and swinging down, or a block released from rest and sliding down a frictionless track, the conservation of mechanical energy gives us mgy turing into ½ mv2, ie. mgyi = ½ mvf2. You can see a lab/demo using photogate timers to show you that the 2 balls in the demo end up with the same speed (same reading from the photogate timers).
