FRAMING OF STATEMENTS

STATEMENT -1 : Net force on a particle w.r.t an inertial frame does notdepend on the velocity of the intertial frame. , STATEMENT - 2 : If net force on A is vec(F)_(A) and net force on B is vec(F)_(B) then force on A w.r.t B is (ven(F)_(A) - vec(F)_(B)) . STATEMENT - 2 : If acceleration of A is vec(a)_(A) and acceleration of B is vec(a)_(B) then, the acceleration of A w.r.t B is ( vec(a)_(A) - vec(a)_(B))

NON-INERTIAL FRAME OF REFERENCE

STATEMENT -1 : Real forces are frame independent . STATEMENT - 2 : Pseudo force is frame dependent . STATEMENT -3 : Pseudo force is not is real force .

Choose the correct combination of true (T) or fale (F) for the statements. STATEMENT-1: A particle may be accelerating in a reference frame even if net extermal force on the particle is zero. STATEMENT-2: Newton's laws are valid only in frames at rest. STATEMENT-3: Work done by a force depends on reference frame.

STATEMENT-1 : The total momentum of a system in C -frame is always zero. and STATEMENT-2 : The total kinetic energy of a system in C -frame is always zero.

STATEMENT-1 Work done by static friction in any reference frame is zero STATEMENT-2 If work done on the body is positive its kinetic energy increases.

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.

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.

STATEMENT-1 Work done by a force depends on the frame of reference. STATEMENT-2 Displacement of a body is different in different frames of reference.
