Assertion: If net force on a system is zero, then momentum of every individual body remains constant. Reason: If momentum of a system is constant, then kinetic energy of the system may change.

Assertion: To conserve linear momentum of a system, no force should act on the system. Reason: If net force on a system is zero, its linear momentum should remain constant.

Statement 1: Two spheres undergo a perfectly elastic collision. The kinetic energy of system of both spheres is always constant. [There is no external force on system of both spheres]. Statement 2: If net external force on a system is zero, the velocity of centre of mass remains constant.

A : If net force acting-on a system is zero, then work done on the system may be nonzero. R : Internal forces acting on a system can increase its kinetic energy.
