Question

what is inertial frames of reference ?

Answer 1

Here u go my friend
An inertial frame of reference in classical physics and special relativity is a frame of reference in which a body with zero net force acting upon it is not accelerating; that is, such a body is at rest or it is moving at a constant speed in a straight line.

All inertial frames are in a state of constant, rectilinear motion with respect to one another; an accelerometer moving with any of them would detect zero acceleration.

Hey mate ^_^

=======
Answer:
=======

=> Inertial frame of reference a reference frame which is either at rest or in uninform motion along the straight line of accelerating frame of reference is called and inertial frame of reference.

=> All the fundamental laws of Physics have been formulated in respect of inertial frame of reference.
