Momentum is regarded as Mass in motion. In other words, when an object moves, it inherits momentum. The momentum is given as the product of the mass and the velocity. The change in momentum is given as the impulse. The momentum of a system remains conserved if there is no external force...
Conservation of angular momentum is a physical property of a spinning system such that its spin remains constant unless it is acted upon by an externaltorque; put another way, the speed of rotation is constant as long as net torque is zero. Angular momentum, sometimes referred to as spin, i...
