Answer» ____________________________________________________________→The shapes of cars and planes are streamlined . Why ? => The shapes of cars and planes are streamlined . This is because when an object MOVES through air , it EXPERIENCES frictional force that resists the motion of the BODY. In such a case , streamlined shape reduces the frictional force and helps in movement . [ NOTE - Frictional force is a contact force that comes to play when a Body moves or tends to move over the surface of ANOTHER body. ] __________________________________________________________ |
