Given an initial state in which we know both K and U, and asked to calculate one of these quantities in some final state, we simply equate the sums at each state:U o + K o = U f + K f . Such a relation further bypasses our kinematics laws, and makes calculations in conservative sy ...

... Therefore to move a mass m up to a height (h) above the ground you will need to move a force F (= mg) through a distance h and so this needs mgh joules of energy. So if it takes that amount of energy to get it up then its gravitational potential energy is also mgh because it will release that energy ...
