Momentum is conserved --
Question 48 options:
only in elastic collisions of bodies
in all mechanical systems under all conditions
only in inelastic collisions of bodies
only in systems for which the net external force is zero
only in systems for which gravity is the only force.
If only one option can be selected then:
only in systems for which the net external force is zero
If more than one can be selected then also include
only in elastic collisions of bodies
