5 Household Cleaners That Are Toxic To Your Dog. Cleaning your home is important, but itâs also important that you use cleaners that will not harm you or your dog. While some household chemicals and cleaning products are safe, there are others that are extremely toxic and can cause serious harm, or even death, to your pets.
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.
Interference Drag, which may occur where surfaces with different characteristics meet (e.g. wing and fuselage) Induced Drag, which is a secondary effect of the production of lift, and. Wave Drag which comes into play when shock waves are developed close to the surface of the aircraft in transonic and supersonic flight. Drag and Airspeed Parasitic drag increases with the square of the airspeed, while induced drag, being a function of lift, is greatest when maximum lift is being developed, usually at low speeds.
