... Since the individual angular momentum can change, the total angular momentum of the system can change. Both internal and external forces can provide torque to individual particles. However, the internal forces do not generate net torque due to Newton’s third law. Let’s consider a two particle system ...

... 10. If an object is at rest, no forces are acting on the object. 11. Only animate objects can exert a force. Thus, if an object is at rest on a table, no forces are acting on it. 12. Force is a property of an object. An object has force, and when it runs out of force it stops moving. 13. The motion ...
