4-2 Gravitational potential energy Conservation of energy can be understood only if we have the formula for all of its forms. I wish to discuss the formula for gravitational energy near the surface of the Earth, and I wish to derive this formula in a way which has nothing to do with ...
Explain gravitational potential energy in terms of work done against gravity. Show that the gravitational potential energy of an object of mass m at height h on Earth is given by PEg = mgh. Show how knowledge of the potential energy as a function of position can be used to simplify calculat...

In this paper, we derived expressions of the relativistic potential energy for radial, circular and general curvilinear motion of a mass under the influence of a gravitational field, and the equivalence relationship between velocity and radius in each case. Also it was obtained the influence of ...
Physics definition Physics definition Speed: the distance moved per unit time.Average speed: the total distance travelled in the total time taken.Velocity: the change in distance in a specified direction per unit time. / the change in displacement per unit time.Displacement: distance in a ...
4-3 Kinetic energy To illustrate another type of energy we consider a pendulum (Fig. 4-7). If we pull the mass aside and release it, it swings back and forth. In its motion, it loses height in going from either end to the center. Where does the potential energy go? Gravitational en...
