... This basically states that if you have two point masses, the force of the 2nd on the first is proportional to each of their masses, is inversely proportional to the square of their distances, and is attractive (i.e. directed towards the other). One very useful property of the fact that the force is ...

Potential energy
... 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 ...

Introduction to Thermodynamics
... First Law of Thermodynamics Energy is a property of any system, and changes in this property can be deduced from the conservation-of-energy principle. The work needed to change an adiabatic system from one specified state to another is the same however the work is done (mountain climbing analogy). ...
