So P sqrt2mK Law of Conservation of Linear Momentum. FracdPdt fracmvdt mfracdvdt ma F_net. The Law of Momentum Conservation The above equation is one statement of the law of momentum conservation.
Momentum is equal to the mass of an object multiplied by its velocity and is equivalent to the force required to bring the object to a stop in a unit length of time.
Final momentum m 1 v 1 m 2 v 2. Initial momentum m 1 u 1 m 2 u 2. The linear momentum balance equation in terms of material stress follows directly by substituting into this equation for Sij in terms of Sij The angular momentum balance equation can be derived simply by substituting into the momentum balance equation in terms of Cauchy stress sij sji 55 Work done by Cauchy stresses. Linear Momentum Dimensional Formula.
