Abstract
In modern physics it is considered, that in a rotating body the moments of pulses mvR compensate each other. Hence the total moment of a pulse of a rotating body is equal to zero. It means that the weight of a body does not increase at rotation. At a level of the moments of pulses it is correct, but without attention there is a centrifugal acceleration. Even if the elementary particle has a spin, why a massive rotating body cannot have own moment of a pulse which is caused by centrifugal acceleration instead of tangential speeds? There is a question: if the weight of a body "increases" as a result of growth of linear speed why the weight cannot increase as a result of centrifugal acceleration? This elementary growth of weight as a result of rotation of a body about the axis is not taken into account in modern theories. The existing theory considers only the general influence of "cross-section" force on acceleration of a body as a whole, and centripetal acceleration inside a bodyappears not in a field of vision. In result there is "deficiency" of weight. But this deficiency is taken into account by a principle of equivalence. According to this principle, on the person placed in a centrifuge, the same force operates as though he falls from height . Considering a principle of equivalence, it turns out, that the body develops at rotation the more capacity, than at linear movement with the same speed.
