Wind moves the blades of a windmill through the principle of aerodynamics. The shape of the windmill blades is designed like an airfoil, with a curved surface. As the wind flows over the blades, it creates areas of high and low pressure. The pressure difference results in a lift force, similar to the lift on an airplane wing. This lift force causes the blades to rotate. The wind’s kinetic energy is thus converted into mechanical energy, turning the rotor connected to a generator, producing electricity. The design ensures optimal utilization of wind energy to generate power in a sustainable manner.
Kinetic energy is the energy possessed by an object due to its motion. It depends on both the object's mass and its velocity. The formula for kinetic energy (KE) is KE = 0.5 × mass × velocity². Essentially, the greater the mass and velocity of an object, the higher its kinetic energy. Objects in motRead more
Kinetic energy is the energy possessed by an object due to its motion. It depends on both the object’s mass and its velocity. The formula for kinetic energy (KE) is KE = 0.5 × mass × velocity². Essentially, the greater the mass and velocity of an object, the higher its kinetic energy. Objects in motion possess kinetic energy, and this energy is directly proportional to the speed and mass of the object. When an object accelerates or decelerates, its kinetic energy changes, reflecting the dynamic relationship between motion and the energy inherent in that motion.
