Deconstruct- Physics, Calculate the speed of the electrons using the curve…

- - - - Measurements, of data and consistency of such
      - If multiple motors are made as variable, there is a high likely hood of random error as small deviations in the creation will lead to differing outputs form the motors.
      - Differing remaining amount of battery capacity/ remaining charge. Will result in different mathematical outcomes of identical motors.
    - - One D cell battery
      - Enamelled copper wire-thin gauge
      - Insulation tape and wire side cutters.
      - Two paperclips and three rubber bands
      - Sandpaper square and wooden dowel (approximately 3cm in diameter). We used a whiteboard marker!
      - Neodymium magnet-button magnets may not be strong enough for you
- - - - The radius of the uniform circular motion (r)
      - Velocity of the rotating mass (v=2pi*r/T)
      - The weight Force (W=mg)
        
        This will be the weight on the opposite end of the string to the bung, and will also be the tension force applied upon the spring, which is also the centripetal force in this case.
      - Mass of Rotating Object (m)
    - - Thread the string though the pipe, leaving ample length on both ends for the attachment of the bung and weight.
        
        Attach the weight to one end of the string in a sufficient enough manner that it will be able to withstand the future force and weight that will be applied to it.
        
        Now on the opposite end of the bung with the string still threaded trough the pipe attach the weight on the opposite end the rope.
        
        now carefully with the weight and bung attach on opposite ends of the rope whilst still threaded through the pipe swing the bung around on top having it make a circle.
        
        Now have an observer count the amount of revolutions the bung has completed with a stopwatch. Then when the count has reached ten pause the stopwatch and record the time (T).
        
        Now stop the bung by pinching the end of the sting with the rubber stopper where it meets the pipe, then record distance between the bung and the pipe (r).
      - Maths
    - - Small plastic/rubber pipe approx 10cm in length
      - Rope or string that will comfortably thread through the pipe, around 50cm in length
      - A rubber bung/ stopper that can be attached to the string
      - A weight, that can be attached to opposite end of the string, its weight values does not need to be know but it would support findings
      - A stopwatch
- - - - Cardboard
      - Scissors
      - CD or DVD
      - Box cutter
      - Glue or Sticky tape
      - Spectrometer template: https://www.fizzicseducation.com.au/wp-content/uploads/2025/01/Spectroscope-template.pdf
    - - Print out the spectrometer template. Using the glue, stick the template onto the cardboard.
        
        Cut the CD into the shape onto the template. Be careful when cutting the CD so that the reflective part does not peel off. Now glue down the CD onto the template where it says insert CD here.
        
        Cut a thin slit where it says “cut slit” on the template using the scissors.
        
        Fold on all the hard lines upwards
        
        Fold the base into a box without the lid, you can either glue where it says “paste”, however we find that sticky tape is stronger.
        
        Fold the lid and place it on top, ensure there is a gap left between the side closest to the CD, this will be the observation point to look through. Now tape or glue the sides together.
- - - - Then plugin in the knowns and the mass of the weight is found, and then if the true weight of is wanted divide the found value by g
