... The sudden change in relative air speed causes a large and sudden change in the lift generated by air speed past the wing. This can be enough to cause a stall. The aerofoil shape is only part of the lift generated by the wing. The transfer of momentum from air incident on the surface of the wing als ...

Work and Kinetic Energy
... As an example of the distinction between this definition of work and our everyday understanding of the word, consider holding a heavy chair at arm’s length for 3 min. At the end of this time interval, your tired arms may lead you to think that you have done a considerable amount of work on the chair. ...

... Thus, work has the same unit as energy, the joule. To further illustrate the relationship between energy and work, let’s consider the bouncing tennis ball in Figure 6.2. First, we have to do work to raise the ball to its starting position. That is, we have to apply an upward force on the ball to ove ...
