notes5 Potential Energy Conservation
... This indicates that the potential energy change from position 1 to position 2 (i.e., the gain) ΔU=U2-U1 is equal to negative of the work done by the gravitational force W1-2 to move the mass from position 1 to position. For the mass to gain gravitational potential energy (i.e., ΔU=U2-U1>0), gravita ...
