What is the relationship of lift‚ drag‚ thrust‚ and weight when the airplane is in straight-and-level flight? Lift equals weight and thrust equals drag. During the transition from straight-and-level flight to a climb‚ the angle of attack is increased and lift is momentarily increased. During a steady climb‚ the angle of climb depends on excess thrust. A propeller rotating clockwise‚ as seen from the rear‚ creates a spiraling slipstream that tends to rotate the aircraft to

Baden. The different types of shapes affect the aerodynamics of a basketball. Although at first it may sound strange‚ the motion of a basketball when it leaves the hands of a player is governed by the same physical laws of an airplane. There are multiple ways to affect the aerodynamics of the ball like the flick of the wrist‚ force and the quickness of the release when you shoot. The texture of a basketball as well as the weight can play on the aerodynamics of the basketball and can affect the rotation

Enjoy Learn and align with Curriculum September 2008 Paper Wings Guidelines This may look ridiculous and appear to be a child’s play. As you use the kit and build your first plane‚ you will realize that it is not all that simple. Soon you will learn to make the plane to fly and discover the joy of flying. In the process you will learn the nuances of flying intuitively. This
