![]() ![]() This is what happened to the modified plane-it experienced a greater amount of drag, which pushed it back more than the original plane. You could probably feel this, as your hand would be more forcefully pushed back as the car moves forward. ![]() When your hand is held out vertically, it catches a greater amount of air and experiences a greater drag than when it is horizontal. For example, this is what happens when you're in a moving car with your hand out the window and you change its position from horizontal to vertical. In this activity you increased how much drag acted on the paper plane by making a one-inch-high vertical strip on both wings. The force of the air pushing your hand back as you move forward is drag, also sometimes referred to as air resistance. To think about drag, imagine you are in a moving car and you put your hand out the window. How does this affect the plane's flight? Does adding paper clips somewhere make its flight better or much worse?ĭid the original plane fly the farthest? Did the plane with increased drag fly a much shorter distance?Īs a paper plane moves through the air, the air pushes against the plane, slowing it down. ![]() Try adding a paper clip (or multiple paper clips) to different parts of your paper plane (such as the front, back, middle or wings) and then flying it.
