Question

distinguish between inertial and non inertial frames of reference ​

Answer 1

if u r in a frame having constant velocity or at rest then you are in an inertial frame
if you are in a frame that has an acceleration then you are in a non inertial frame
Newton's laws are valid for inertial frame only and they are not at all valid for non inertial frame

Answer 2

Answer

⚫Inertial Frame of Reference

◾Acceleration of this frame of reference is always zero.

◾Newton's laws of motions holds good.

◾Fundamental experiments in physics when performed in this frame in any direction, give the same result.

⚫Non Inertial Frame of Reference.

◾Acceleration with respect to some frame of reference.

◾Newton's law of motion do not hold good.

◾Experiments yields different results.

Example 1 ; fictious Force is an accelerating lift upwards and downwards does not give the same result.

2. Weightlessness experienced by astronauts.
