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

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

Answer: (C)

Solution

An inertial frame is one that is not accelerating (it moves with constant velocity relative to the ground, approximately an inertial frame), so Newton's first law holds in it. The bus moving with constant velocity has zero acceleration, so the driver is in an
