What does a large surface area of a parachute create?

A large surface area of a parachute creates a large resistive force due to air resistance, also known as drag. When the parachute is deployed, the increased surface area encounters more air molecules as it falls through the atmosphere, effectively increasing the amount of resistance against the force of gravity. This resistive force acts upward, opposing the downward motion caused by gravity.

The large resistive force is critical for the function of a parachute, as it slows down the descent of the person or object it carries, allowing for a safer landing. This principle is based on the relationships between surface area, speed, and air resistance; larger surfaces can displace more air, resulting in a more significant drag force.

In contrast, a smaller surface area would lead to less air resistance, thus a smaller resistive force. Understanding this principle is key to grasping how parachutes and other forms of drag-based slowing mechanisms work in physics.
