on a moving Skateboard then jump up, the board keeps going in the same direction with you. Would the same happen if you stood in the aisle of of an Aeroplane. If was at the front of the plane and jumped up would you end up at the back of the plane? And if not, why not?

H = I.I.R.T
i.e. H is directly proportional to R

Also, H = V.V.T / R
i.e. H is inversely proportional to R....

How is this possible? Please explain...
