Wind Turbines |
Keywords: kinetic energy, power, wind energy, wind turbines Can wind turbines actually be used to harness a substantial amount of power? The total energy available in wind and the power that can feasibly be extracted from it will be determined using the fundamentals of kinematics. Following, the limitations of location and machinery of wind turbines that restrict the amount of power that can be harnessed will be examined, before comparing the impact of wind energy with various other common sources of energy.

Using spreadsheets |
Keywords: absolute and relative cell references, chi-squared, Excel, formulas, graphing, model, OpenOffice Calc, simulating data, Solver, spreadsheets, trend line, uncertainties Want a quick way to do calculations, simulate data and draw graphs? Here are some quck tips on using spreadsheets to do this! In this activity, we will use an accepted physical model, that of an object falling in a vacuum, to create simulated data that could result from an experiment. We will then graph this data and fit a trend line to it. Read More... |
