Applying Newton`s Laws
... ** Note: The value of the acceleration depends on the frame of reference. Newton’s Laws are only valid when frame is an inertial reference frame. Technically a set of axes fixed to the Earth is not an inertial reference frame due to the rotation of the Earth, but the Earth’s rotation is very slow th ...
