In physics, the center of mass of a distribution of mass in space (sometimes referred to as the balance point) is the unique point at any given time where the weighted relative position of the distributed mass sums to zero. This is the point to which a force may be applied to cause a linear acceleration without an angular acceleration. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where the entire mass o… Webb12 maj 2015 · Linear velocity of the center of mass is v c m = v A + ω × r c m where r c m is the location of the center of mass relative to A. Linear momentum in terms of the motion of A is P = m ( v A + ω × r c m) P = m v A − m r c m × ω Angular momentum at A is L A = L c m + r c m × P which is expanded as
