How a Parachute Slows a Fall

1Have you ever dropped a flat sheet of paper and a crumpled paper ball at the same time? The ball hits the floor first, even though both are made of the same kind of paper. The flat sheet drifts down slowly. The reason is the same reason a parachute works.

2When anything falls, gravity pulls it down toward the ground. But the air does not simply get out of the way. As an object falls, it pushes against the air, and the air pushes back. This push is called air resistance. A wide, flat object pushes against more air than a small, tight one. It gets more air resistance, so it falls more slowly.

3A parachute uses this idea. Its main part is a large piece of light, strong cloth called a canopy. Before it opens, the canopy is folded into a small pack. When it opens, air rushes inside, and the canopy spreads wide into a dome shape. Now a huge surface is pushing against the air, and the fall slows down a lot.

4Long cords called lines connect the canopy to a harness that the person wears. Many round parachutes also have a small hole at the top. The hole lets a little air escape in a steady way. This helps keep the parachute from rocking from side to side.

5Parachutes have many jobs. Skydivers use them to land gently after jumping from an airplane. Some parachutes carry boxes of food and supplies down to places that are hard to reach by road. Some spacecraft also use giant parachutes to slow down before they splash into the ocean.
