Arm and leg weakness can be caused by a variety of different conditions, some of them temporary and others chronic. Excessive exercise is one cause of temporary fatigue in the major muscle groups, although this is not considered true muscle weakness.
Mass is an intrinsic property of the body and gravity is the force exerted on any body by the things that surround it. Weight, on the other hâ¦and, depends on gravity. It is equal to the product of the mass of the body and the gravitational force acting on it.
The force of gravity is the force exerted by the gravitational field of a massive object on any body within the vicinity of its surface.This force is dependent on three factors: the mass of the massive object, the mass of the smaller body, and the separation between the two, measured between their geometrical centers. 1 = mass of the first object (lets assume itâs of the massive one). m 2 = mass of the second object (lets assume itâs of the smaller one). r = the separation between the two masses. Notice that the gravitational force is directly proportional to m 1.
