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.
Friction is a force that acts against a moving object to slow it down. A type of friction is air resistance. Friction opposes the direction in which the object is moving, causing the object to decrease in speed, or stop all together. All kinds of friction cause moving objects to slow down or stop. Friction can be quantified as a force resisting motion which is proportional to the weight of the object, for an object lying on a flat surface. The frictional force is found by multiplying the objects weight by a coefficient of friction, which is usually less than one, but can be higher than one (for example with rubber tyres on dry tarmac).
