Frame OF References

Work Depends On The Frame Of Reference

Statement-I : Time period of spring block system is the same whether in an accelerated or in an inertial frame of reference. Statement-II : Mass of the block of spring block system and spring constant of the spring are independent of the acceleration of the frame of reference.

Reference Frame

STATEMENT-1 : Acceleration of a particle in a reference frame may be non- zero , even if net external force acting on the particle is zero. and STATEMENT : 2 In a non- - inertial reference frame, Newton's second law is not valid.

Inertial and Non Inertial Frame||Pseudo Force

Statement I: A particle is found to be a rest when seen from a frame S_(1) and moving with a constant velocity when seen from another frame S_(2) . We can say both the frames are inertial. Statement II: All frames moving uniformly with respect to an inertial frame are themselves inertial.

STATEMENT-1 : The relation vectau=(dvecL)/(dt) is applicable in centre of mass frame, even though the centre of mass is accelerating. and STATEMENT-2 : The relation vectau=(dvecL)/(dt) can be directly applied in a non-inertial frame.

The no.of correct statements are 1) The apparent weight of a freely falling body is zero II) Applied force is a example of pseudo force III) Pseudo forces exist for observers only in non inertial frames, such forces have no existence relative to an inertial frame
