What does having no external force on a closed system mean? For example if I have 2 objects colliding. One travels at a constant speed while the other travels with a constant acceleration. In this case is an external force being applied on the system?
If so, only the m1u1+m2u2=m1v1+m2v2 can be used if the two objects have a constant velocity?
Also, during the collision won't there be a force being applied on the object? So how would momentum be conserved? During the collision the formula F=change in mv/time is used. So is the conservation only after this collision?
Thanks for the help :smile:
