The Change in potential energy of a mas, asit moves from poisition y1 to position y2 in the presence of constant forceFcanbe written deltaU=-F(y2-y1).Use this relation toshow that the change in gravitational potential energy of mass m between ground level, and distance h above the ground is given by delta U=mgh regardless of wheter you choose the positive y-driection to be in the upward direction or the downward direction
