- - - - Friction
      - Tension
      - Air resistance
      - Normal contact forces
  - - - Gravitational
      - Electrostatic
      - Magnetic
  - - - Wear goggle
      - Hang the spring from a stamp and a clamp
      - Measure its length with ruler
      - Hang empty slotted mass carrier and measure the new length of spring
      - Keep adding the slotting masses, measure new length each time
- - - - Materials that allow the flow of electric charge
        
        Graphite
        
        Copper
        
        Most metals
    - - Materials that do not allow the flow of electric charge
        
        Cork
        
        Felt
        
        Cardboard
        
        Plastic
    - - Set up the circuits as shown in the diagram
      - Record the resistance of the thermistor at room temperature
      - Place in hot water, record the resistance as the water cools at ever 5 degrees celsius temperature drop
      - Record your results in a table
  - - - Measured on volts (V) on a voltmeter
      - Voltage=Work done/charge or V=W/Q
      - Voltage=Work done/energy transferred or V=W/E
- - - - Find the mass of container and liquid
      - Subtract mass of container from mass of container and liquid
      - Measure amount of liquid
      - Density will be Mass/Volume=Density (M/V=P)
    - - Find the mass of container, liquid and the object
      - Fill the container to the top with the liquid
      - Place the object in the liquid
      - Measure the liquid displaced by the object
      - Density will be Mass/Volume=Density (M/V=P)
    - - To find the density of a regular object we need to find the mass of the object and the volume of the object
      - To find the mass of the object, place the object on a top-pan balance and record the mass
      - To find the volume of the object
        
        Measure length, width and height
        
        Calculate volume using V=LxWxH
      - Find the density using density=mass/volume
  - - - The particles can only escape if near surface and enough kinetic energy to break their liquid bond
      - All temperatures and has a cooling effect
    - - Any more energy breaks liquid bonds for all particles throughout
      - It occurs at boiling point of the liquid and no cooling effect so the temperature is constant
    - - The pressure of a gas is inversely proportional to the volume. If the volume increases, then the pressure decreases.
