When a conservative force does positive work on a body, the potential energy of the body

Underline the correct alterntaive: a) when a conservative force does positivie work on a body, the potential energy of the body increase/decreases/remains unaltered. work done by a body against friction always results in a loss of its kinetic /potential energy. c) The rate of change of total momentum of a many-particle system is proportional to the external force/ sum of the internal forces on the system. d) In an inelastic collision of two bodies, the quantities which do not change after the collision are the total kinetic energy/total linear momentum/total enregy of the system of two bodies.

When a conservation force does positive work on a body, then the

STATEMENT-1 When a conservative force performs positive work on a body, potential energy of the system decreases. STATEMENT-2 Work done by a conservative force does not produce any change in kinetic energy.
