Practicals of Interest - Coggle Diagram

- - - - Launch Angle - Changing the launch angle may change the horizontal range. What angle creates the greatest horizontal range?
      - Initial Velocity - Changing the initial velocity may change the horizontal range. Test whether v is directly proportional to sh
      - Time of Flight - Changing the height of release to increase time of flight and thus increase horizontal range
    - - Paper
      - Blue Carbon Paper
      - Projectile Launcher/Projectile
    - - Air Resistance - This is an uncontrollable variable that will have major impacts on the overall results and thus range
      - Bernoulli's Theorem - Rotational movement of the projectile in the air as it passes through the air
  - - - Mass - Changing the mass to test how this impacts the total momentum conserved
      - Velocity - Changing the velocity of the cart to determine how the momentum changes
    - - Carts
      - Track
      - Light gates
      - Weights
    - - Friction - As the carts are moving along a track, they will have friction with the air and the surface of the track
- - - - d=wavelength*L/retention factor
      - Wavelength must be controlled as this is directly proportional to d and the width of the slit
        
        Green and Red Laser available in the classroom
      - L could be changed to get three different graphs of different breeds of dog
      - d must be controlled for each breed (i.e same dog hair used for each trial of that breed)
    - - 3 dog hair of different breeds
      - Red Laser
      - AC/DC Power
      - Paper
    - - Genetic Factors
        
        Position of the hair
        
        Age of dog
        
        Colour/pigment
      - Laser may not be exact
- - - - Weight hanging below the table
      - Mass of object spinning on the surface
      - Radius of the circle
    - - Larger mass hanging below the table
      - Glass tube
      - Smaller mass on the table surface
      - String
    - - Reaction Time - Timing the objects motion will mean reaction time may impact the overall results
      - Air Resistance - The object will experience drag as it moves in a circular motion and also against the surface. The table used would not be frictionless and thus would cause the object to decelerate as it moves in circular motion
- - - - Number of coils
      - Type of metal coil
      - Type of battery
      - Radius of the circle
    - - Copper coil
      - Battery
      - Tape
      - Stopwatch
    - - Purity of the copper coil: As a magnetic and electric field is produced between the battery and the copper coil, the results will be determined based on the purity of the copper coil metal. As this will not be entirely pure due to oxidation, this will impact the results
      - Strength/Life of the battery: An electric field will be produced by the battery when it passes through the coils. Thus, the strength of the battery will influence this electric field.
      - Magnetic field in the air: As the batteries will be accelerated by the change in magnetic flux between the copper coils, the charge and magnetic field of air particles may disrupt the motion of the battery as it passes through the coil
