These measure wind speed. You can build a DIY version using paper cups, straws, and a pencil. As the wind blows, the cups spin, and the rotations per minute can be calculated to determine speed.

Simple tools like a weighted index card can also serve as basic indicators of wind force. 3. Harnessing Wind for Energy get wind

To understand wind, we must measure its speed and direction using specific instruments: These measure wind speed

Wind is air in motion, primarily caused by the uneven heating of the Earth's surface by the sun. This creates pressure differences where air naturally moves from high-pressure areas to low-pressure areas. the cups spin
