This statement means that if a closed system is not affected by external forces, its total linear momentum does not change. Object Momentum Calculator The momentum of the object is equal to the product of the objects mass m by its speed v, the direction of the momentum coincides with the direction of the speed vector. ![]() However, it can be proved that in any inertial frame, it is a conserved quantity, which follows from the fundamental property of space homogeneity. It can be seen from the definition that the momentum of an object depends on the frame of reference. It states that the rate of change of a body’s momentum is equal to the net force applied to the body. The most important physical law in which the momentum of an object appears is Newton’s second law of motion. The momentum of a system of objects is the vector sum of their momenta. $$\overrightarrow p = m \overrightarrow v.$$ In Newtonian mechanics, the momentum \(\overrightarrow p\) of an object is equal to the product of the mass \(m\) of this object and its velocity \(\overrightarrow v\), the direction of the momentum coincides with the direction of the velocity vector: Linear momentum ( translational momentum, or simply momentum) is a vector physical quantity, which is a measure of the mechanical motion of an object.
