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.
When an object free falls, it does not encounter a significant force of air resistance. Always Some Air Resistance. However, a falling object is going to run into some degree of air resistance. Air resistance is the outcome of collisions between the objectâs leading surface and air molecules. How much air resistance the object encounters depends on the speed the object is traveling and the cross sectional area of the object. When the object is falling faster, this increases air resistance.
