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.

Non-inertial frame of reference have

Non-inertial frame of reference have

The acceleration of a particle is zero as measured from an inertial frame of reference. Can we conclude that no force acts on the particle?

The acceleration of a particle is zero as measured from an inertial frame of reference. Can we conclude that no force acts on the particle?

The acceleration of a particle is zero as measured from an inertial frame of referecne. Can we conclude that no force acts on the particle?

If the resultant of all the external forces acting on a system of particles is zero. Then from an inertial frame, one can surely say that

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.
