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.
F = force of gravity. G = gravitational constant. m 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. 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.
