Difference between Inertial frame of reference and Non inertial frame of reference. |
|
Answer» Inertial frame of reference : (a) A frame of reference which is at rest or which is moving with a uniform velocity along a straight line is called an inertial frame of reference. (b) In inertial frame of reference Newton’s laws of motion holds good. (c) Ideally no inertial frame exist in universe. For practical purpose a frame of reference may be considered as inertial it it’s acceleration is negligible with respect to the acceleration of the object to be observed. Example : The lift at rest, lift moving (up or down) with constant velocity. Non inertial frame of reference : (a) Accelerated frame of references are called non-inertial frame of reference. (b) Newton’s laws of motion are not applicable in non-inertial frame of reference. Example : Car moving in uniform circular motion, lift which is moving upward or downward with some acceleration, plane which is taking off. |
