You are walking and about to go up an escalator. The escalator is not in function and so there is no speed difference in the ground.
However, upon stepping on it, a common experience is to “feel” the jolt as if the speed differential is there.
The same happens when stepping off.
The effect seems to happen to a large range of people and persists even if one walks with their eyes closed.
Why is this?
In: Engineering
The treads of an escalator are about 1 cm or so below below the surface of the floor. Step off from (or onto) a 1cm board and you’ll feel the same jolt as your foot falls farther than (or stops sooner than) your brain expected it to.
