In a closed system, two moving bodies collide. There are no external forces acting on thesystem. How does the total momentum of the system before the collision compare with the totalmomentum of the system after the collision?

(1 point)
The total momentum after the collision is more than the total momentum before the collision.
The total momentum after the collision is the same as the total momentum before the collision.
The total momentum after the collision is less than the total momentum before the collision.
The total momentum after the collision is zero, while the total momentum before the collision is
nonzero.

In a closed system with no external forces acting on it, the total momentum of the system is conserved. This means that the total momentum before the collision is equal to the total momentum after the collision.

Therefore, the correct answer is: The total momentum after the collision is the same as the total momentum before the collision.
