- - - - e.g. an increase in the mass of load hung on the spring does not increase the extension of the spring
    - - e.g the spring will not return to the original length after the weights/loads are)removed
    - - e.g for the same load hung on spring___ and spring__,spring___ extends more/ less than spring_
- - - - magnets
        
        writing structure for magnets:
        
        magnets have 2 poles
        
        north
        
        like poles attract and unlike poles repel
        
        south
        
        cannot attract non-magnetic materials like:
        
        plastic
        
        glass
        
        wood
        
        can attract magnetic materials like:
        
        nickel
        
        iron
        
        can all be magnetised by the stroke method or the electrical method to make a temporary magnet
        
        cobalt
        
        steel
        
        rest in the north- south direction when freely suspended
        
        magnets can act at a distance
  - - - spring
        
        when we push the spring downwards, the spring gets compressed .The elastic spring force would move in the direction which pushes the spring back to its original shape.
        
        the extension of the spring id the length of spring which tells us how much the spring is stretched when a load is hung on it.
        
        the total length of spring which makes up both the original length of spring and the extension of the spring total length of spring =original length of spring+extension of spring
      - rubber band
  - - - water resistance
      - air resistance
  - - - basically ,it pulls objects towards earth
    - - weight is determined by this formula.:
        
        9.8N x mass
