ABSTRACT
Linear kinetics involves a variety of concepts that refer to invisible forces and their visible effects on bodies at rest and in motion. A great deal of movement can be explained by kinematics and linear kinetics. Kinetics is the area of biomechanics where the source of motion is studied. Gymnasts also need to consider that they can produce forces from muscle tension and these forces can be seen in accelerating limbs and body. Inertia is a property of a body to remain in one place or to continue in uniform straight-line motion unless acted upon by an outside force. It may seem counterintuitive, but an object at rest and an object in straight-line uniform motion are actually examples of the same thing – inertia. Inertia is proportional to mass so a more massive objects, whether at rest or in straight-line uniform motion, exhibits greater reluctance to move than a less massive object.
