All planes need air to pressure under their wings to stay up in the air. As they move forward. The higher air pressure underneath their wings pushes them upward and gives them lift. The smooth, streamlined shape of the plane allows the air to flows easily over its surface. This helps to reduce the drag caused by the air pushing against the plane and allows it to move rapidly through the air. Planes move forward using engines. This movement is called thrust. Moving forward keeps a stream of moving air passing over the wings. If the engines fail, the planes will begin to descend very quickly. The air above the wing moves faster, so it is at a lower pressure than the air under the wing.The air under the wing moves more slowly and is slightly squashed, so it is at a higher pressure than the air above the wing. Which statement is false according the text?
- Planes movement forward is calling as streamlined.
- Moving forward keeps a stream of moving air passing over the wings
- Streamlined shape of the plane allows the air to flows easily over its surface
- All planes need air to presure under their wings to stay up in the air
- Semua jawaban benar
