Today in science we made paper airplanes. We had to include the four forces of fight in our observations. If it had too much Drag then it wouldn't stay in the air for a long time, if you had too much gravity the same thing would happen, if you had too much thrust then it would bang in to the ceiling, if it had too much lift pretty much the same thing would happen. Here are the definitions.
- Lift a positive force caused by air pressure on the wing.
- Thrust is a force that proples an object forward.
- Gravity is a force that causes objects to go down.
- Drag is a resistance of air for anything to move through it.
My best plane had all forces in it my plane was called the Hammer. My second best plane had to much lift. Here's a question for everyone: What was your best plane and what forces did it have? See you all tomorrow. Have a Great night! From: Bridget
