define collision of two moving ball and the law of conservation of momentum
Answers
★The law of momentum conservation can be stated as follows.
★For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.
Two balls of mass m1 and m2, with velocities v1 and v2 collide head on. ... For this to happen, both masses must have equal and opposite momentum, or m1v1 = m2v2. Thus, in a completely inelastic collision in which m1v1 = m2v2, both masses will be stationary after the collision.
The law of conservation of angular momentum states that the angular momentum of a body that is the product of its moment of inertia about the axis of rotation and its angular velocity about the same axis, cannot change unless an external torque acts on the system.
