__________ 1. The total energy of the boulder on top of
the hill is zero.
__________ 2. If the boulder rolls downwards, the total
mechanical energy at any point along its path is constant.
__________ 3. As the boulder rolls downwards, its kinetic
energy increases.
__________ 4. The potential energy of the boulder
decreases as it moves down.
__________ 5. At any point along the downward path of
the boulder, the total energy is equal to the sum of the
potential and kinetic energy.
