Moments

We started pressure and moments today, and completed a practical on moments.  You need to remember that a moment is the turning effect of a force, and can be calculated by using the formula:

moment (Newton meters) = Force (newtons) x Distance from pivot (meters).

 So to lift or move something thats heavy using a lever you can either use more force or lengthen the distance between teh force (where you are pushing) and the pivot.  Tomorrow we will be using this to cover more material so make sure you know how to use the equation.
