"Sabrina" Physics
I studied about Newton's Third Law of Motion and how it works. Newton's Third Law of Motion "for every action, there is an equal and opposite reaction.
Investigation #1/Experiment #1 The first experiment that I did was breaking a board with my elbow. I never knew that when you try to break a board that it actually puts force on you just like you put force on the board. That's something I never thought about. The breaking of the board sums up how Newton's Third Law of motion was implied.
Experiment #2 This experiment I did was breaking a stick. The stick was a lot more flexible but still broke. I broke it with my knee and it snapped in half. If you put force on an object, its going to put a force on you.
Experiment #3 During this experience I broke a pencil. The smaller an object is, the harder it is to break it. So again Newton's third law applies. In conclusion, If you ever tried to break something and you had lots of struggles, now you know that Newton’s Third law of Motion applies
Scouts and Engineering I did Aviation. Aviation is about aircraft's. The official meaning of aircraft is "a weight-carrying structure for navigation of the air that is supported either by its own weight/buoyancy or by the dynamic action of the air against its surfaces." Two types of air craft’s are Lighter-than-air an rotor-crafts. Lighter-than-air might be balloons, or zeppelins. Rotor crafts might be helicopters or Gyro planes. There are five different operations that I learned. A piston, a Turboprop, a jet engine, a turbo fan, and a Scram Jet. I will just talk about the Piston. The process a piston goes through is intake, compression, ignition, power, and then exhaust. I also learned how each the primary surface (ailerons, elevators, and rudders) affect the airplanes attitude. I will talk about one. The elevator is called pitch. On the tail/ lateral axis, the stick/ joy stick is connected by means of wires or hydraulics to the tail section or the elevator. By moving the stick, the pilot can change the position of the elevators translating. There are six degrees of freedom. The ventilated slat, sealed slat, droop nose, Kruger slant, triple slotted flap, double flap, Aug mentor flap, and the single slotted flap. http://gameinary.webs.com/sabrina.html Did you know that airfoils generate lift by using air displacement? I do, well now! Two instruments that are found in single-engine aircraft. An Altimeter and an airspeed indicator are instruments in an airplane. An altimeter measures the max elevations in the mountains but it won’t find any small obstacles. You have to set it to the local Berimatic setting. When the air pressure changes, it changes into Altitude. The airspeed indicator tells you the speed you are going through the air. The wing on an airplane cares about airspeed not ground. The ground doesn’t get you very far, but the air/ win in the sky helps you take off by pushing against, above, an below the plane’s wing(s). This is very necessary to help the plane. In conclusion, I think Aviation is a class you should take if you want to become a pilot or just want more knowledge about aircraft's or just things that fly. I think that the class tells you a lot about this topic, and shall help you out a lot.
