Question and answer
Expain the action of a parachute
Simply put: A parachute is a device that creates air resistance as it is moved through the air. This resistance is determined by the surface area of the device and the speed of it's movement. If the assembly is falling, [ at a certain speed the resistance equals the force of gravity, and the speed is constant. A low constant speed allows a load to survive a fall that might otherwise destroy it. ]
