Air resistance, also called drag, is the forces that are in opposition to the relative motion of an object through the air. Drag forces act opposite to the oncoming flow velocity. Drag, unlike other resistive forces, depends directly on velocity. Drag is the component of the net aerodynamic force acting opposite to the direction of the movement and the forces working perpendicular are called lift.
Electric forced air heating systems. An electric forced air system is a single heating unit controlled by a single thermostat that supplies heat to the entire house by fan-forced air through duct work. Ducts are often concealed in crawlspaces, attics or walls and deliver heat through an adjustable register.lectric forced air systems generate heat through high resistance wires called heating elements. Electricity flowing through the elements generates heat that is distributed throughout your home by a fan or blower which forces air through the elements, and directs the heated air into the ductwork.
