Chapter 6 Fictitious Forces { observed force pseudo observed ma ma F ma ma F c c = + = a a c y with respect to the elevator is constant. radius r is constant as your car moves in a circle, your position with respect to the car interior is constant. You can move the acceleration arising from the non-inertial reference frame to the other side of the equation to find equivalent force observed force pseudo elevator elevator observed ma ma F ma ma F = + = 43 42 1 Chapter 6 Fictitious Forces g m r T r r v a c 2 = 0 cos : sin : 2 = = mg T y r v m T x θ Strictly speaking the forces on the swinging mass don’t balance, a force is needed to maintain the centripetal acceleration of the object as it moves on a circular orbit.
