    Ch. 14. energy conservation
    The ultimate bobsled experience
    Forces and component vectors solve the first part ...
    A moving object has kinetic energy
    The kinetic energy is related to the velocity
    Calculate the velocity using energy conservation and the change in height
    You've used energy conservation to solve the second part
    Putting on the brake does work on the track
    Energy conservation helps you to do complicated problems in a simpler way
    There's a practical difference between momentum and kinetic energy
    Question Clinic: The "Show that" Question
    Question Clinic: The "Energy transfer" Question
    Momentum conservation will solve an inelastic collision problem
    You need a second equation for an elastic collision
    Energy conservation gives you the second equation that you need!
    Factoring involves putting in parentheses
    In an elastic collision, the relative velocity reverses
    There's a gravity-defying trick shot to sort out ...
    The initial collision is inelastic - so mechanical energy isn't conserved
    Use momentum conservation for the inelastic part
    Question Clinic: The "Ballistic pendulum" Question
