How does an open parachute slow a skydiver's fall?
The parachute pulls the skydiver up.
The parachute changes the mass of the skydiver.
The parachute increases the force opposing gravity.
The parachute weakens the force of gravity.
The correct answer is:
The parachute increases the force opposing gravity.
When an open parachute catches the air, it creates drag force that counteracts the force of gravity pulling the skydiver downward. This drag force slows down the skydiver's fall, allowing for a safer and softer landing.
