Every airplane has to reach a takeoff speed, at which lift overcomes gravity. The takeoff speed depends on how much weight a particular airplane carries. Besides, the airplane’s propeller or jet engine also has to provide enough thrust to overcome the drag caused by the friction between passing air and the wing.
