Study Notes
Forces in Flight
- A force is a push or pull that can cause an object to change its motion or shape.
Flight Mechanics
- For an airplane to takeoff, thrust must be greater than weight.
- For an airplane to land, thrust must be less than weight.
Wing Function
- The function of wings in flying is to produce lift, which is an upward force that counteracts the weight of the airplane.
Engine Role
- The role of engines in flying is to produce thrust, which is a forward force that propels the airplane forward.
Human vs. Bird Flight
- Human flight differs from bird flight in that humans use machines to generate lift and thrust, whereas birds use their wings to generate lift and thrust through flapping.
Space Environment
- Air is absent in the near vacuum of space.
Spacecraft Operations
- A spacecraft uses rockets to reach space and maneuver.
- A spacecraft does not have weight in orbit because it is in a state of continuous fall around the Earth, but it does have mass.
