Question

prove law of conservation of momentum​

Answer 1

Explanation:

hey dear...

Law of conservation of momentum states that

total momentum of system remains conserved in the absence of external force. Proof: Consider a body of mass m1 moving with veocity striking against another body of mass m2 moving with velocity . Let, the two bodies remain in contact with each other for a small interval

Alternative Title: law of constant momentum

Conservation of momentum, general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains constant. 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. For any array of several objects, the total momentum is the sum of the individual momenta. There is a peculiarity, however, in that momentum is a vector, involving both the direction and the magnitude of motion, so that the momenta of objects going in opposite directions can cancel to yield an overall sum of zero
