- - - - Great engineer, Leonardo Da Vinci
        was the first to ever make an attempt at
        a flying machine, he made many sketches and
        eventually came up with a design that seemed good
      - He called this design the onithopter, and it was
        controlled by flapping objects that were like bird wings,
        it seemed like a good design but did not work
      - The onithopter did not work, as a human was too
        heavy and they could not flap the wings fast enough
    - - The hot air balloon was invented by
        brothers, Joseph and Etienne Montgolfier, this
        invention was actually succesful
      - The first succesful flight of the ballloon lasted for around 10 minutes, and they managed to succesfully fly around 1.2miles
  - - - In 1880, Da Vinc's Ornithopter was remade
        by a man named otto lilienthal, he attempted to keep the ornithopters same design, however
        he made it more practical
      - He redesigned the Ornithopter as a glider, and managed to make over 2000 successful flights wiith the glider,
      - After this glider was created, it began to convince society that flight was actually achievable within the very near future
    - - In 1903, the Wright Brothers managed to make the first ever sustained powered flight
      - This flight was in the world's first
        aeroplane, and set the groundwork for most aviation today
      - In the 1950's, aviations was developped some much, that it went out of the Earth's atmosphere in the form of space technology
- - - - Bernoulli theroized that as the velocity
        of a fluid such as air, increased, the pressure
        decreased,
      - Bernoulli's Principle Is best shown in a
        Venturi tube, where the ends are larger and have high pressure, and low velocity, however, the middle is smaller and has low pressure but very high velocity.
      - Throughout this process, the total energy of the airstream is conserved. An increase in velocity is accompanied by a decrease in pressure.
    - - Newtons Second Law: A force is equal to the change in momenutm, per change in time - F = M*A
      - Netwons Third Law: Every force applied to an object is opposed by an equal force in the opposite direction, or as it is often stated, for every action there is an equal and opposite reaction.
      - Newtons First Law: An object in motion or rest will stay
        in it's current state until acted upon by another force which will then make it change the objects current state because of these forces that are impressed on it
  - - - Gyroscope: Used to stop the
        drone from titlting to much
        in a certain direction
        and correct this tilt, it is
        also used to find the angle of a drone
      - Accelorometer: Used to measure the
        speed of a drone in different directions
        these directions are Roll, Pitch and Yaw
      - IMU or inertial measurement unit: This
        sensor contains 3 gryscopes and 3 acceloromters
        to measure the orientation of a drone in the three
        directions, Roll, Pitch, and Yaw
      - GPS or Global Positioning System: Used
        to pinpoint the exact location of a drone, this
        is helpful in autonmous flying, to know where
        the drone is actually going
      - Obstacle Avoidance: Used to detect oncoming obstacles
        in the drones path to make sure that it will not crash into
        anything on its journey
    - - Thrust is the forward motion of an object in motion,
        the more thrust an object has the faster it goes
        foraward
      - Drag is the opposite of thrust, which means
        it is the backwards motion, the more drag
        there is on a flying object, the lest forward thrust it has.
      - Lift, this is the vertical pull of the plane
        that determines how much the plane is being
        pulled up
      - Weight is the downwards force that pulls
        down on an object in flight, the more weight there is
        the less lift there is, as these two are oposite forces
