Neglecting air resistance, an object dropped from a moving vehicle retains the horizontal velocity of the vehicle at the moment of release. Relative to the moving vehicle (the pilot's frame of reference), the object only has a vertical velocity component due to gravity.
A bomb is dropped at a point from a moving aeroplane. The pilot observes that
