Momentum - We know that all moving objects possess momentum. Momentum of the body is defined as the product of its mass and the velocity. Now let us see how kinetic energy of a body is related to its momentum. Consider a body of mass 'm' moving with..

The law of conservation of momentum states that the total vector sum of momenta of bodies, in an isolated system, along any straight line remains conserved and remains unchanged due to reaction forces between the forces of the syste..

If no external torque acts upon a system, then the angular momentum of the system remains constan..

Law of Conservation of Momentum - From Newton's third law of motion we know that whenever a force is applied on a body there will be an equal and opposite reaction. Action and reaction forces result in change in velocities of both the bodies which in turn change the momenta of t..

From Newton's third law of motion we know that whenever a force is applied on a body there will be an equal and opposite reaction. Action and reaction forces result in change in velocities of both the bodies which in turn change the momenta of these bodies. In an elastic collision the initial ..

From (1) we get, which is the law of conservation of momentum. Generalising to n particles, The law of conservation of momentum states that the total vector sum of momenta of bodies, in an isolated system, along any straight line remains conserved a..
