two objects collide and bounce apart. assuming no outside forces act on the system, which best describes the total momentum after the collision?\nit is always greater than it was before the collision.\nit is often greater than it was before the collision.\nit is always the same as it was before the collision.\nit is often the same as it was before the collision.
Answer
Brief Explanations:
According to the law of conservation of momentum, in a closed - system (where no outside forces act), the total momentum before and after a collision remains the same.
Answer:
It is always the same as it was before the collision.
