Predict \& Explain Ball 1 is dropped to the ground from rest. Ball 2 is thrown
to the ground with an initial downward speed. Assuming that the balls have the
same mass and are released from the same height, is
the change in gravitational potential energy of ball 1
greater than, less than, or equal to the change in
gravitational potential energy of ball 2? (b) Choose the
best explanation from among the following:
A. Ball 2 has the greater total energy, and therefore more
of its energy can go into gravitational potential energy.
b. The gravitational potential energy depends only on the
mass of the ball and its initial height above the ground.
C. All of the initial energy of ball 1 is gravitational
potential energy.
