They both are accelerating frames of reference. To the passenger - its indistinguishable! Einstein’s inductive leap here was the realization that perhaps the forces are indistinguishable because they are. This can be seen as an observational illusion: the elevator floor can be seen to either be accelerating upwards at 9.81 m/s/s or the passenger could be seen as falling towards the floor. Then the elevator floor would rise up to meet him at 9.81 m/s/s. An initial resistance would be felt the ground, or elevator floor, would recede away from him at 9.81 m/s/s until he has traveled enough distance to expend the force given by jumping. If the passenger were to jump in the elevator while it was accelerating upwards at 9.81 m/s/s (the rate at which we are pulled to the earth by gravitational forces) he would observe the same effect as if he was jumping on the earth. Comparatively, another pseudo-force like this arises from a rotating reference frame, say if one is on a spinning carnival ride one would presumably feel a pull away from the center.Ĭonsider the scenario of this elevator accelerating upwards at 9.81 m/s/s. Einstein hypothesised that since this pull, caused by the momentum of the passenger fighting against his acceleration, is indistinguishable from gravitational influences, it is only logical to assume that they are one and the same phenomenon. Recall that a body at rest tends to stay at rest. When the elevator starts accelerating upwards, a pull downwards is felt by the passenger. One of these thoughts experiments in particular involved a solitary passenger on an elevator that is alone in the universe.

In a thought experiment, a premise is assumed to deduct from it the possible consequences. For every action there is an equal and opposite reaction.Įinstein was fond of a form of inquiry known as thought experiments.The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
