The total work done on a particle is equal to the change in its mechanical energy

STATEMENT-1: Work done by the net force acting on a particle is equal to the change in its kinetic energy. STATEMENT-2: Change in potential energy is always equal to the work done by external forces. STATEMENT-3: Work energy theorem is not applicable, if the work is done by the non-conservative forces

Assertion :- According work energy theorem net work done on a body is equal to change in its kinetic energy. Reason :- The work energy theorem is independent of Newton's second law.

According to the work energy theorem, the work done by the net force on a particle is equal to the change in its

Statement -1: The work done by all forces on a system equals to the change in kinetic energy of that system . This statement is true even if nonconservative forces act on the system. Statement -2: The total work done by internal forces may be positive.

Asseration : Displacement time graph of a particle moving in a straight line is shown in figure. Work done by all the forces between time interval t_(1) and t_(2) is definitely zero. , Reason : Work done by all the forces is equal to change in kinetic energy.
