physics unit 1 - Coggle Diagram

- - - - regular obj like cube/cuboid
        
        measure the height, width and length then multiply them together
      - irregular obj
        
        drop them into a measuring cylinder with liquid and measure how much the volume increases
  - - - si units stand for Le Système International d'Unités
        
        or The International System of Units
      - and litres
        
        ml, l
      - si units are:
        
        m, km, cm, mm
        
        g, mg, kg
        
        m2, km2, cm2, mm2
        
        m3, km3, cm3, mm3
        
        note that 1 litres = 1 dm3, 1 mililitres = 1 cm3
- - - - the "p" here is rho in greek
      - the si unit is kg/m3
  - - - use a scale to find the mass of the cylinder
        
        reset the scale to 0 and pour liquid in it and measure the mass
      - you already have the volume from the cylinder
- - - - hands move around a clock face, a traditional clock
        
        to find time, find where the hands are and decode them
        
        records infinite numbers of specific time, but usually overshadowed becuz too fast
    - - gives time in numerals
        
        usually record to a hundredth of a second
        
        the time is literally given to you
