How does a parachute reduce the terminal velocity of a person falling through the air?
A parachute increases air resistance, which is proportional to the surface area of the parachute. This increased air resistance slows down the person's fall, reducing their terminal velocity. By the time the person reaches terminal velocity with the parachute open, the gravitational force pulling them down is balanced by the air resistance force pushing up, allowing for a controlled descent.
Why does a person loss speed if he opens parachute?
When a person opens a parachute, it creates drag or air resistance which slows down the descent rate. The larger the parachute, the more drag is created, and the slower the person falls. This helps to reduce the speed and control the descent for a safe landing.
How is acceleration due to gravity be zero in a parachute?
In the case of a parachute, the person and parachute fall at a constant speed once the forces acting on them are balanced. This means that the net acceleration, including gravity, is zero. Gravity is still acting on the person and parachute, but it is balanced by the drag force exerted by the parachute, resulting in a constant speed descent.
When a parachute opens why do they slow down?
When a parachute opens, it increases air resistance, which creates drag that opposes the force of gravity pulling the person or object down. The larger surface area of the parachute allows it to catch more air, which helps to slow down the descent of the person or object safely.
What is the terminal speed of a person falling with an open parachute?
The terminal speed of a person falling with an open parachute is typically around 12-15 mph (about 19-24 km/h). At this speed, the force of air resistance acting on the person is equal to the force of gravity pulling them down, resulting in a constant velocity.

Why does when two people jump from an airplaine with the same size parachute the more massive person will have a greater final terminal velocity?
The two masses give the downward force, the upward force is due to the friction of the parachute ... and you stated that the chutes were identical.
Where could a person buy parachute cord?
Parachute cord can be purchased at any local Army & Navy store. It can also be found online at many of the larger sporting/outdoor equipment providers.
How does terminal velocity affect a falling person with a parachute?
Terminal velocity is the constant speed reached by an object falling through the atmosphere when the force of air resistance matches the force of gravity. Parachutes increase air resistance, allowing a person to reach terminal velocity at a slower speed. This slower fall reduces the impact force when landing, making it safer for the person.
What mechanism is used in parachute?
A parachute works by catching air in its canopy, creating drag and slowing down the descent of an object or person. The canopy is designed to create enough drag to decrease the terminal velocity of the falling object, allowing for a safe landing. The parachute harnesses the force of air resistance to counteract the force of gravity.
When a person skydives from very high distance does the speed in which they are falling continue to increase the entire way down?
After about 10 seconds you reach terminal velocity your speed remains constant till the parachute opens.
Why a person without a parachute falls fast than a person without a parachute falling from same height?
if there is no air then both will take same time.But due to presence of air person who is without parachute will take less time.
What will happen if a parachutist opens its parachute before reaching its terminal velocity?
During free fall, the parachutist reaches a terminal velocity (a constant velocity) of somewhere between 120 and 180 miles per hour. (If you go feet first, you go faster than if you lie on your back or front). When the parachute opens (hopefully), the terminal speed is reduced to around 12 miles/hour.
