The fact that you feel heavier when when the "up" elevator starts up or the "down" elevator comes to a halt is a consequence of inertial forces. The fact that you feel lighter when the "down" elevator starts down or the "up" elevator comes to a halt is also a consequence of inertial forces. Inertial forces press you into the seat when you accelerate away from a traffic light, pushes your head toward the windshield when you slam on the brakes, and pushes you across the seat when you turn a sharp curve. In each case, your reference frame accelerates.

How many fictitious forces does nature require? Nature requires at least one fictitious force for every object in every accelerated reference frame.
