Define inertial and non-inertial frames.
-A system of co-ordinates along with time as a unit whose axes can be suitably chosen for physical or mathematical analysis is known as a frame of reference
-Inertial Frame is a frame of reference either at rest or moving with a uniform velocity i.e with zero acceleration is known as inertial frame.
-All the laws of physics are obeyed well in such a frame.
-Non inertial frame of reference is a frame of reference which is either having a uniform linear acceleration or is being rotated with a uniform speed.
