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.
Mass of Objects. The mass of the two objects, denoted in the above equation as mass1 and mass2, is the first factor that affects the amount of gravity that acts on each of the objects. The larger the masses, the more gravitational force each object exerts on the other. Put simply: the more mass an object has, the more gravity acts on that object.
