Why does a parachute slow you down

How large a parachute is in other words, the parachute's surface area affects its air resistance, or drag force. The larger the parachute, the greater the drag force.

In the case of these parachutes, the drag force is opposite to the force of gravity, so the drag force slows the parachutes down as they fall. Consequently, the larger parachute, with its greater drag force, takes longer to reach the ground than the smaller parachute.

Although the force of gravity is greater on the larger, slightly heavier parachute than the smaller, lighter one, the relative increase in the drag force on the larger parachute is greater than the increase in the force of gravity.

Encourage learners to engage in science practices by raising questions about why their parachutes move in particular ways, or how they could change their parachutes to make them work better. They can then plan and carry out investigations to answer these questions.

You may have to help learners collect, analyze, and interpret their data in order to figure out the answers to their questions. Attribution: Exploratorium Teacher Institute. Connect with us!

How does this apply? Your parachute allows you to descend more slowly because it lowers terminal velocity by increasing your air resistance.

Most parachutes are designed to create a large amount of drag and allow you to land at a safe, low speed. Parachutes today are designed for a myriad of functions. Military operations utilize a parachute that is dome-shaped, providing only basic steering and are used by the military for the insertion of paratroopers and gear.

On the other hand, civilian jumpers most commonly use a rectangular Ram-air parachute, one constructed with a series of tubular cells that inflate as air is forced into each chamber. The result is a semi-rigid, curved airfoil wing that delivers higher performance and increased maneuverability.

These two parachutes are packed within a single backpack-looking apparatus we call the container. The main parachute is deployed by a miniature chute, known as the pilot chute. At the appropriate altitude, a jumper will extract the pilot chute from the elastic pouch, where it is securely stored, sewn on the bottom of the container. The pilot chute inflates and creates enough force to extract the main parachute from the container.
