Answer 2

In ancient times people has sails which helped them to use the force of the wind.

• In addition to the leisure delight cursing affords, it entails a few thrilling physics. Sailing begins coevolved with the pressure of the wind at the sails.
• Analyzing that interplay yields a few outcomes now no longer typically acknowledged to non-sailors.
• It turns out, for example, that downwind isn't always the quickest path for cruising. And there are aerodynamic issues.
• Sails and keels paintings via way of means of providing “lift” from the fluid passing around them. So optimizing keel and wing shapes entails wing theory.
• The resistance skilled via way of means of a transferring sailboat consists of the consequences of waves, eddies, and turbulence withinside the water, and of the vortices produced in the air via way of means of the sails.
• To lessen resistance efficaciously via way of means of optimizing hulls, keels, and sails, one has to recognize its numerous components.
