In Physics, potential energy (PE) is said to be equal to a product of mass (m) in Kilograms, Acceleration due to gravity (g) in m/s 2 and height (h) in meters. That is, Potential Energy (P.E) = mgh. This type of energy is present in every object which has a mass and position within a force field and has a kinetic energy of zero relative to other objects.
Apr 21, 2008 · the object's mass - more mass means more rotational inertia, and; how the object's mass is arranged relative to the axis of rotation - if the mass is farther from the axis, you get more rotational inertia. Suppose that you have several round objects that have the same mass and radius, but made in different shapes.
