non intertial frame

In non inertial frames,Newton's second law of motion is written as where a= acceleration of the body, relative to the non-inertial fram and F_(p) is the pseudo force.

Assuming earth to be an intertial frame, an example for inertial frame observer is:

In which of the following cases , the observer is in intertial frame?

Define inertial frame and non-inertial frame. Is earth an inertial frame of reference?

Asseration : Work-energy theorem can be applied for non-inertial frames also. Reason : Earth is a non-inertial frame.

Two frame S_(1) and S_(2) are non-inertial. Then frame S_(2) when observed from S_(1) is inertial. A frame in motion is not necessarily a non-inertial frame

Statement I: A concept of pseudo force is valid both for inertial as well as non-inertial frame of reference. Statement II: A frame accelerated with respect to an inertial frame is a non-inertial frame.

Assertion: The driver in a vechicle moving with a constant speed on a straight road is in a non-inertial frame of referance. Reason: A reference frame in which Newton's laws of motion are applicable is non-inertial.

The pilot landing or taking off the aero plane is an inertial observer or non - inertial frame of refrence.
