Forces
  1. Weight and Mass
    1. Mass
      1. This is a measure of how much matter there is in an object
        1. It is measured in Kg
          1. Mass is constant
          2. Weight
            1. WEight is measured in N
              1. WEight is the force gravity exerts on an object
                1. The weight of an object changes from place to place
                  1. Weight = Mass x gravity
                2. Density
                  1. Density = Mass/Volume
                    1. Kg/M^3
                    2. Measuring and Drawing Forces
                      1. Forces are measured in N
                        1. We can measure forces using a Newton Meter
                          1. The larger the force the more the spring extends
                          2. Drawing Forces
                            1. The larger the arrow the larger the force
                          3. Balanced And Unblanced Forces
                            1. Balanced
                              1. The object will remain stationary
                                1. The object will carry on moving at a steady speed
                                2. Unbalanced
                                  1. The object may speed up
                                    1. Slow down
                                      1. Stop moving
                                        1. Start moving
                                          1. Change direction
