Deriving terminal velocity using mathematical terms according to the drag equation as follows: F = b v 2. Where b is the constant depending on the type of drag. ∑ F = m a (free fall of an object) m g − b v 2 = m a (assuming that the free fall is happening in positive direction) m g − b v 2 = m d v d t.
