Have you ever sled down a hill and experienced that force blowing in your face? That, my friend, is air friction (Air Friction: What is it?). Air friction effects our daily lives: for example, when you throw a ball over a fence, you have to throw it hard enough to fight gravity and air friction, if the air friction wasn’t there you wouldn’t have to throw it as hard (The path and Range of a Baseball). Kevin Williams from the Evergreen Science Education Discussion area states that air friction is dependant on the velocity of an object (Re: Air Friction). Air friction is very similar to that of friction as we think of it. It is a force opposite of the direction the object is traveling. It slows the object down, except that this isn’t on a surface, but rather in the air.
