do physics online space gravitational potential energy
... Hence, one can predict the velocity v of the object when it has fallen a distance h starting with an initial velocity u. Equation (2) and (3) are only applicable near the Earth’s surface where the value of the gravitational field strength (acceleration due to gravity) g is a constant. To find a mor ...

... This is called “The First Law of Thermodynamics”. Aside: Actually the First Law of Thermodynamics is this: “heat added plus work done equals change in energy” or Q + W = U . (Q is the symbol for heat). In this chapter we won’t consider adding heat to a system (like holding a flame under it), so Q = ...
