Drafting (aerodynamics)
Drafting is when a moving object like a car or a bike tries to go faster by following closely behind another object. When you ride a bike or drive a car, you have to push through the air in front of you, which slows you down. But if you ride or drive close enough behind another object, it creates a little pocket of air where there isn't any air resistance, so you can go faster without using as much energy.
Imagine you're riding your bike and your friend is riding in front of you. When you ride right behind your friend, you'll notice that it feels a little easier to pedal. This is because you're sitting in the pocket of air that your friend is creating as he or she moves through the air. The closer you are to your friend, the stronger this pocket of air is, and the easier it is for you to ride your bike.
Drafting is especially helpful with very fast-moving objects like cars that are traveling at high speeds. Professional car racers use drafting to save energy and go faster. When one car follows closely behind another, it creates a draft that reduces wind resistance, allowing the following car to go faster than if it were driving on its own. But drafting can be dangerous if the cars are too close or if the driver in front makes a sudden move, so it's important to be careful and only do it when you're trained and experienced enough to do so safely.
