... DETERMINATION OF THE ACCELERATION OF AN ELEVATOR. INTRODUCTION: In order for an object to accelerate, there must be a net force acting on it. We know that the direction of the acceleration will be in the same direction as the direction of the net force. The equation for Newton’s 2nd law is F = ma o ...
