This 5-minute video explains how modern sailboats move forward by generating lift. The video explores the aerodynamic forces generated by two parts of the sailboat: the sails and the keel. These forces, when properly adjusted by the sailor, counteract each other to generate forward movement.
Editor's Note: Old World sailboats relied on wind to push them forward. Modern sailboats are much more complicated, and offer a great opportunity to explore Bernoulli's Principle, lift, and drag. See Related Materials for a teaching module on the physics of sailing and an article from "Physics Central" that explains how to sail faster than the wind speed.

4. The Physical Setting
6-8: 4F/M3a. An unbalanced force acting on an object changes its speed or direction of motion, or both.
9-12: 4F/H4. Whenever one thing exerts a force on another, an equal amount of force is exerted back on it.
8. The Designed World
8B. Materials and Manufacturing
9-12: 8B/H1. Manufacturing processes have been changed by improved tools and techniques based on more thorough scientific understanding, increases in the forces that can be applied and the temperatures that can be reached, and the availability of electronic controls that make operations occur more rapidly and consistently.
