How does a parachute work?
A parachute works by dramatically increasing air resistance to slow a falling person or object safely to the ground. Its wide canopy traps air, creating a large upward drag force that counteracts gravity and lowers the fall to a gentle speed.

Watch a 2-minute animated lesson that shows exactly how a parachute works.
Step by step
- 1The wide canopy catches air as it falls.
- 2Trapped air creates strong upward drag (air resistance).
- 3That drag balances gravity, slowing the descent.
- 4It lowers the terminal velocity to a safe landing speed.
- 5A vent or shape keeps it stable instead of swinging wildly.
Frequently asked questions
- How does a parachute slow you down?
- Its large canopy massively increases air resistance, creating an upward force that balances gravity and reduces your falling speed to a safe level.
- Why is a parachute so big?
- A larger canopy catches more air and generates more drag, which is needed to slow a heavy person enough for a gentle landing.
- Why do some parachutes have a hole in the top?
- A vent lets some air escape steadily, preventing the chute from rocking side to side and keeping the descent stable.
