1. A windmill is a structure that uses wind energy to turn large blades, which rotate a shaft connected to machinery. Traditionally, it grinds grain or pumps water, converting wind's kinetic energy into mechanical energy for various tasks. For more visit here: https://www.tiwariacademy.com/ncert-solutiRead more

  3. A firki (paper pinwheel) demonstrates the effect of wind by spinning when air flows against its blades. The wind's force transfers energy to the blades, causing them to rotate, showing wind's ability to move objects.
