Source sentences:
text: Conservation of momentum is a fundamental law of physics which states that the momentum of a system is constant if there are no external forces acting on the system.
text: Angular momentum is conserved because there are no external torques the satellite must deal with (gravity always acts parallel to the orbital radius).
text: In this lab, you will show that the total momentum of the system is always conserved when there is no net external force acting on the system, and that the total mechanical energy of the system is only conserved in certain kinds of collisions.
text: Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero.
