Explain why internal forces, or those that act within the system of interest of the object under consideration, are not relevant in solving problems related to the Second Law of Motion.
A net external force has no effect in the change in motion. Internal forces, or those responsible for holding a given object together, affect the motion of such an object.
A net external force causes a change in motion. Internal forces, or those responsible for holding a given object together, do not affect the motion of such an object.

- The starship Enterprise has its tractor beam locked onto some valuable debris and is trying to pull it toward the ship. A Klingon battle cruiser and a Romulan warbird are also trying to recover the item by pulling the debris with their tractor beams as shown in Figure P5.25. a. Given the following magnitudes of the tractor beam forces, find the net force experienced by the debris: FEnt = 7.59 106 N, FRom = 2.53 106 N, and FKling = 8.97 105 N. b.
