In a closed system, two moving bodies collide. There are no external forces acting on the system. How does the total momentum of the system before the collision compare with the total momentum of the system after the collision? (1 point)

Question

A. • The total momentum after the collision is less than the total momentum before the collision.
B. • The total momentum after the collision is more than the total momentum before the collision.
C. • The total momentum after the collision is the same as the total momentum before the collision.
D. • The total momentum after the collision is zero, while the total momentum before the collision is nonzero.

Answer 1

C. • The total momentum after the collision is the same as the total momentum before the collision.

In a closed system with no external forces, momentum is conserved, meaning the total momentum before the collision is equal to the total momentum after the collision.
