Imagine 2 cars 1 weighs 1 ton, the other weights 2 tons. If we ignore the effect of the suspension - when both of these cars go over the same bump in the road, which accelerates fastest in the vertical direction?
I would have assumed that the lighter car would - as $a=F/m$, so the car with more mass has a lower acceleration. But inversely - would the force input to both cars be the same? Or would this be mass dependent and both cars would accelerate at the same rate?
I guess in simple terms, I'm asking is the force input constant, or is the acceleration constant between the 2 cars - or something in between?
