Question

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)
Responses

The total momentum after the collision is zero, while the total momentum before the collision is nonzero.
The total momentum after the collision is zero, while the total momentum before the collision is nonzero.

The total momentum after the collision is less than 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 the same as 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 more than the total momentum before the collision.

Answer 1

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

Reason: With no external forces (closed system), momentum is conserved — internal forces between the bodies cancel, so total momentum is unchanged.
