        Hookes law
        
        Deformes
        
        Plastically
        
        limit of proportionality
        
        Elastically
        
        F= kx
      - Newton
        
        3rd law
        
        "For every action there is an equal and opposite reaction"
        
        1st law
        
        "An object remains at stationary or at a constant
        speed unless a resultant force acts on it"
        
        2nd law
        
        Force= mass x acceleration
      - Friction
- - - - String then measure string
    - - Ruler
  - - - ruler, l x h x w
    - - measuring cylinder
    - - put it into a measure cylinder with water and see how much the water rises, difference = volume
- - - - Time= distance/speed
      - Distance= Speed x time
      - Speed= distance/time
    - - Difficulties

      - You need
        
        Stopwatch
        
        Meter stick
        
        Calculator
      - Method
        
        calculate s=d/t
        
        measure distance using a meter stick
        
        measure time it took for the trolley to go through the ramp
    - - Speed= gradient of distance-time graph
      - Area under speed-time graph= distance
- - - - Mass
        
        Mass is measured with a balance
        
        Mass= kg or g
      - Volume
        
        Volume is measured with a ruler (l x h x w)
        
        Volume= cm^3 or m^3
    - - Mass
        
        Mass is measured with a balance
        
        Mass= kg or g
      - Volume
        
        immerse it in water in a beaker with volume markings, and see how much the level goes up.
        
        Volume= cm^3 or m^3
