    Calculate the work done by the system, when 40J heat is supplied to it, the internal energy of system increase 32J .

    There will be decrease in potential energy of the system, if work is done upon the system by

    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.

    Consider the following statements and choose the correct option. I. Potential energy is a conservative force. The change in potential energy is equal to the negative of the work done by the force.

    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.
