Building a Windmill

• This week you will be building a windmill from some common materials

• Your windmill’s job will be to lift a load of nuts and bolts

• You will be calculating the power that your windmill lifting

How to calculate the Power of your windmill

• You will first need to calculate the Energy of your windmill (you have seen this before!)

E=mgh• Then you will multiply this energy by how long it

takes for your windmill to lift the load

P=E/tWhere t=time (s)
