Do bombs have physics

Do bombs have physics? I’ve just played and saw that dropped bomb fell in straight line vertically but plane was in motion horizontally so bomb should follow on arc but it didn’t.

They do, I see a lot of unintentional skip-bombing, and I usually bomb from ~600m alt at a 45 myself so I have to account for it.

sometimes not
once i saw a bomb that literally bounced off my tank and i was already crossing myself
