Seen from a distance, something falling from a great height does it slowly.

An apple falling from a tree lands in a fraction of a second, though close up, the tree appears tall. A very tall building, a kilometre or so away, seems no taller than the tree, but something falling from the top takes seconds to get to the bottom. It seems to go slowly.

That's one reason why children get run over on roads. Something approaching from a distance seems to move slowly as it takes a long time for it to halve the distance to the viewer, causing the size of the object to double in each dimension, or be 4x as big in area. As it gets closer, it halves the distance remaining, faster and faster, until in the last second it gets really really big really really fast and wham!!!

Something far away seems to move slowly.

It's perception, not physics. Nothing to do with members or columns or beams.
