14. Question of the Day #43 True or False -In the absence of external forces momentum is conserved in all types of collisions. -In the absence of external forces KE is conserved in all types of collisions. -In an explosion, momentum and KE of the objects are conserved. -If two identical objects move toward each other at identical speeds, the momentum of the system is zero before the elastic collision and nonzero after. -If friction is a factor in our lab experiment, momentum will not be conserved. -If friction is a factor in our lab experiment, KE will not be conserved. -If crappy equipment is a factor in our lab experiment, we cannot accurately determine if external forces are acting.
