Power is the rate at which energy is converted from one form to another
where power is measured in watts (W), work is measured in joules (J), and time is measured in seconds (s).
In this experiment you will use a wind turbine to do the work of lifting a mass. You will vary the pitch of the blades of the wind turbine and measure the time it takes to lift a mass a given distance. Based on these measurements, you will calculate the mechanical power (in watts) generated by the turbine as it lifts the weights.
Define how power is calculated.
Identify the units that are used to measure power.
Determine the relationship between wind turbine blade pitch and power generated.
Measure the power developed by a wind turbine.
