 * Which of Newton’s Laws describes how drag slows down an airplane?

The four forces of flight are lift, drag, thrust, and then weight. Drag is what slows the airplane down it is the resistends of air. Lift is what rises the airplane. Thrust is what moves or propelles the airplane forward. Then there is the weight the weight is how heavy the airplane is. Drag and weight go againest each other it ables the plane to fly. But for the plane to fly thrust and drag have to be egual and lift and the weight have to be egual. The prepeller or engine on a airplane is how the thrust on an airplane is generated. Newtons third law shows how to thrust an airplane forward. Lift is generated on an airplane by it's wings because in it's wings there is something called an airfoil and the low pressure moves over top the airfoil and the high pressure goes underneath the airfoil. An airfoil is an object in te airplanes wing that helps it fly. Bernouli's principle is htought to create the lift of an airplane. Drag goes againest the air so it can slow the airplane down. Newtons first law describes drag and how it works. Thrust and lift is needed to keep the airplane in the air.
