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.
Parasitic drag increases with the square of the speed through the air. The second basic type of drag is less obvious, but very important. This type is called induced drag and is related to the wing's production of lift. The net lift, or aerodynamic force of a wing is produced at right angles to the chord of the wing.
