Pick the true statement: Momentum and energy are always conserved in a collision between two objects.   If two identical objects of mass m are traveling with the same speed, they have the same momentum.   An object experiencing a constant force F over a time interval dt will experience a momentum change dp=F/dt.   Momentum of a system is not conserved when a net external force acts upon the system.
