A parachute is a device designed to slow down the descent of a person or object through the air. It typically consists of a large fabric canopy that opens up when deployed, creating drag and allowing for a safer landing. Parachutes are commonly used in activities like skydiving and military operations. The basic principle behind a parachute is air resistance, which increases as the parachute expands. This resistance counteracts the force of gravity, reducing the speed of descent. Parachutes can be made from various materials, including nylon, and come in different shapes and sizes depending on their intended use.
