Final answer:
In collisions, momentum must be conserved for each object according to the law of conservation of momentum.
Explanation:
Momentum is conserved in collisions according to the law of conservation of momentum. After two objects collide and bounce apart, momentum should always be kept constant for each object. This means that the total momentum before the collision should equal the total momentum after the collision, even if the objects change direction or speed.
