[gurpmrtv] Simulating a rolling ball

Simulate a ball rolling on an uneven surface.  Probably easy is speed changing with height to conserve energy, gravitational force acting in the direction of the gradient (steepest).

More difficult: the ball can jump, losing contact with the ground; the ball spins and can skid with friction if the direction of the ball's rotation is not the rolling direction.
