Source sentences:
text: Note that "isolated" means that no external force acts on the system, which is a set of interacting objects.
text: Together with the conservation laws described earlier, this provides a powerful tool for calculating the forces acting on a system.
text: Since no external forces act on the system, its center of mass does not accelerate (Newton's First Law)!
text: Since no external forces act on the system, the velocity of the center of mass of the bullet + block system remains constant.
text: i.e., Total linear momentum before collision is equal to total linear momentum after collision, if no external force acts on the system.
text: After all, if no external forces act on a system, its total momentum will be conserved.
