Conservation of Energy: Racing Marbles
A marble will roll on different paths, starting and ending at the same height. Students will predict and then measure the final velocities of the marble. Ramp A is the nearly horizontal ramp, and Ramp B dips down in the middle. Because the ramps start and end at the same elevation, a marble rolled on Ramp A will end with the same velocity as one rolled on Ramp B, even though they take different times to complete the trip.
