Which of the following person is in an inertial frame of reference?

(A)A pilot in an aeroplane which is taking off.
(B)A driver driving a bus which is moving with constant velocity.Correct
(C)A child revolving in a merry - go - round.
(D)A man in a train which is slowing down to stop.

Answer: (B)

Solution

An inertial frame is one that is not accelerating, i.e. it is at rest or moves with constant velocity relative to another inertial frame (Newton's first law holds in it). The bus moving with constant velocity has zero acceleration, so the driver is in an inertial frame, option (B). The aeroplane taking
