Question

Generally Vectors in physics depends on frame of reference but scalars do not depend on frame of reference.....
Answer the following :--
(i) A scalar quantity which depend on frame of reference....
(ii) A vector quantity which does not depend on frame of reference...
​

Answer 1

Answer:

★ Inertial Reference Frames are reference frames in which Newton first law of motion holds i.e. an object at rest and an object in motion remains in motion unless acted by a net force. An inertial reference frame is either at rest or moves with a constant velocity.

★A non-inertial reference frame is a reference frame that is accelerating, either in a linear fashion or rotating around some axis.

† Examples:

1. A train moving with constant velocity. (Inertial)

2. A rotating merry-go-round. (Non-Inertial)

3. A turning car with constant speed (Non-Inertial)

4. The rotating Earth (Non-Inertial)

Answer 2

Hii

you are welcome in my ans

1) inertial frame :- From were the reference point is taken which cannot be changed .

Newton law hold

2) Non inertial frame :- which is not fixed and are acceleration , velocity etc

cannot hold Newton law
