The potential energy of a system can be negative. You drop a ball to the ground

Question

The potential energy of a system can be negative. You drop a ball to the ground from rest, and, from the same height, throw a second identical ball down to the ground. Their change in gravitational potential energies are different. If the force on an object is zero, the potential energy of the system Is zero. When air resistance is taken Into account, a ball thrown directly upward spends more time on the down than on the way up. If the potential energy of the system is zero, the force on the object is zero.
