Hi
This question is taken from the book Classical mechanics by Gregory.
Please clear this doubt
TIA
-------------
Suppose that a reference frame fixed to the Earth is exactly inertial. Which of the following are then inertial frames ?
A frame fixed to a motor car which is
(i) moving with constant speed around a flat race track
(ii) moving with constant speed along a straight undulating road
(iii) moving with constant speed up a constant gradient
(iv) freewheeling down a hill
Ans (iii). In the other cases, the frame is accelrating or rotating relative to the earth.
The question is :
Why is (ii) not an inertial frame
