A student asked me why bumps feel less bumpy when the car is traveling at a
higher speed. Do shock absorbers absorb quick vertical accelerations better
than slow ones? Is it the inertia of the car which doesn't let it bob up
and down rapidly (as in a seismograph?)
Because of the theory of relativity, I suspect we respond physiologically to
accelerations, rather than to velocity or distance. Is that correct, or
naive?
I am thinking of taking this question on the road -- literally-- using a
CBL with accelerometer to try to determine if there actually IS less
vertical acceleration at higher horizontal speed, or if this is somehow a
subjective phenomena.
