Homework Help: Need helllllp!

  1. Mar 6, 2008 #1
    need urgent helllllp!

    im in year 12 at the moment and our new physics teacher has set us an assignment. it is very deceptively simple he informs us.
    it reads: does a marble at the top of a ramp convert all of its potential energy up the top, into kinetic energy at the bottom of the ramp.....or something along those lines. he has given us a hint by telling us "predictions". he says we can either do simple calculations and get 50% or find out what he wants from this and achieve an awesome result. i cant seem to see what he wants us to find out so anyone's help would be greatly appreciated??? he has given us a ramp and a marble....
    im stuck pleeeeease help!

    It seems you need to measure the speed of the marble at the bottom. Maybe measure how long it takes to cover a certain horizontal distance once it left the ramp?

    Maybe the teacher is asking whether there are some ways that energy might be lost by the system as the marble rolls down.

    Those being things like air resistence or maybe some minor heat or sound
