Asseration : Work-energy theorem can be applied for non-inertial frames also. Reason : Earth is a non-inertial frame.

Work energy theorem is applicable

State the work-energy theorem

Antonym is valid in

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.

Statement I: A concept of pseudo force is valid both for inertial as well as non-inertial frame of reference. Statement II: A frame accelerated with respect to an inertial frame is a non-inertial frame.

A : The change in kinetic energy of a particle is equal to the work done on it by the net force. R : The work-energy theorem can be used only in conservative field.

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

(A) : A reference frame attached to earth is a non inertial frame of reference. (R) : The reference frame which has an acceleration is called a non inertial frame of reference.
