Question

What are the inertial and non inertial frames of references?

Answer 1

Inertial Frame Of Reference :- The Frame Of reference which is at rest is called Inertial Frame of Reference.

Non Inertial Frame Of Reference:- The frame of reference which is not at rest is called Non Inertial Frame Of Reference.

For E.g. :-

If you are standing still i.e. at rest, and then , if you observe a body moving or at rest, then your frame of Reference is called INERTIAL FRAME

If you are sitting in a car (you are in motion w.r.t Ground) , and then you observe a body , your Frame of Reference will be called Non Inertial Frame Of Reference

Answer 2

$\huge \mathfrak{Answer:-}$

$\large\underline\mathrm\red{Inertial \: frame \: of \: reference}$

Those co - ordinate axis whose acceleration is zero is known as inertial frame of refrance. In this case frame may be in rest or morning with constant velocity the frame doesn't rotate. Newton's law is valued only in this frame of refrance.

$\huge \mathfrak\red{Note:-}$

By def earth is a non - inertial frame but all the motion are measured in this earth frame so it behave like the inertial frame.

$\large\underline\mathrm\red{Non \: - \: ineritial \: frame:-}$

Those co - ordinate system whose acceleration is not equal to zero are called the non ineritial frame. In this case frame Newton's law is not valid.

$\large\underline\mathrm\red{Acc^n \: doesn't \: equal \: to \: zero.}$

In this case co - ordinate axis are moving with some acceleration of a st. road or in rotation.
