Assertion (A): Mass and energy are not conserved separately, but are conserved as a single entity called mass energy. 
Reason (R): Mass and energy conservation can be obtained by Einstein equation for energy.
Assertion (A): The Work-Energy theorem is applicable for non-inertial frames also.
Reason (R): The Work-Energy theorem is applicable to non-inertial frames provided we include the pseudo forces in the calculation of the net force acting on the body under consideration.
