Airplanes use the same forces and physical principles as birds to fly. Discover how man has copied nature to achieve flight.
- Flight occurs when the upward force (lift) is greater than the downward.
- Flight is explained by Newton's third law.
- Lift is achieved due to the shape of the plane's wing.
