Inertial and Non Inertial Frame||Pseudo Force

Inertial Mass

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

Inertial Frame Of Reference

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.

The no.of correct statements are 1) The apparent weight of a freely falling body is zero II) Applied force is a example of pseudo force III) Pseudo forces exist for observers only in non inertial frames, such forces have no existence relative to an inertial frame

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

Consider the following two statements A and B and identify the correct choice in the given choices (A) Centripetal force, centrifugal force are equal in magnitude and opposite in direction but they are not force of action and force of reaction respectively because both act on same body. (B) Centrifugal force is a pseudo force in both inertial frame of reference and non inertial frame of reference.
