The main purpose of a parachute is to slow down the descent of an object or person through the atmosphere, allowing for a safe landing. Parachutes work by creating drag, which counteracts the force of gravity as the parachute opens and expands upon deployment. This increases air resistance, reducing the falling speed significantly. Parachutes are commonly used in skydiving, military operations, and emergency situations such as ejecting from aircraft. The design and materials of parachutes can vary significantly, influencing their performance and safety features. When used correctly, parachutes provide a reliable means of descent for various activities.
