1.	What do you mean by inertial frame of reference? Why is it so important?
Answer» Any frame of reference in which Newton's laws of motion are valid, and can describe the dynamics of moving objects, is called an inertial frame of reference. It is important due to the following reasons: (a) All the fundamental laws of physics have been formulated in respect of inertial frame of reference. (b) All the fundamental laws of physics can be so expressed as to have the same mathematical form in all inertial frames of references. (c) The mathematical and optical experiments performed in any inertial frame in any direction will always yield the same results. This property is known as the isotropic property of the inertial frame of reference.
