It depends on the type of collision
|
Detailed explanation-1: -When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum.
Detailed explanation-2: -An object’s momentum before collision is given by P = mv. In the absence of external force, its motion and momentum do not vary before the collision.
Detailed explanation-3: -When two objects collide, their total momentum does not change. The total momentum, before and after the collision, equals the sum of the objects’ individual momenta. For each object, this momentum is the product of its mass and its velocity, measured in kilogram meters per second.
Detailed explanation-4: -The total momentum of the two objects before and after a collision between object 1 and object 2 in an isolated system is equal to the total momentum of the two objects after the collision.
