Experiment 4 Part III: Conservation of Energy
QUESTION 1: Draw a free body diagram for the
mass while it is on the middle of the
track. Label all forces.
QUESTION 2(a): Write down the equation for the
mechanical energy when the mass is at
the top of the track (just before it is
2(b): Write down the equation for the
energy of the mass as it emerges
from the bottom of the track.
2(c): Do you expect these energies to be
the same or different? Why?
