Explain how a parachute works using the terms air resistance surface area and gravity?

A parachute works as the gravity allows the parachute to go up into the air, then the surface area is covered with air resistance.

Name something that needs to travel slowly through air how does it manage this?
A skydiver - he uses a parachute that slows him down as a result of air resistance acting on the surface of the parachute
Would a Parachute work on the moon?
A parachute works on Earth by effectively 'trapping air' inside of it, creating a large surface area and so a large amount of wind resistance or friction. As there is no atmosphere on the moon, there is no air to be trapped and therefore no friction. So no, a parachute would not work on the moon.A parachute works using air resistence. There is no air on the moon. Therefore a parachute would only pull you down faster. If ur planning on going to the moon i suggest you try a jetpack.
Why air resistance acts in the opposite direction of gravity?
Yes, air resistance acts in the opposite direction as an object in motion. (It's air resistance.) In aeronautical terms, we call it drag. Generally, air resistance refers to the effects created on an object moving through it that in some way work to "limit" the object's motion. The air is "just there" and the movement of an object through it sets up the conditions to create air resistance.
Why would friction affect gravity?
Gravitational acceleration is a constant value for a celestial body, and doesn't depend on air resistance/friction. The value on Earth is constant anywhere on Earth, just like the value on Mars is constant anywhere on Mars. In practical,however, this is different. Air resistance lowers the value of gravitational acceleration.
How do air resistance and gravity affect a falling object?
Objects when falling that cannot ignore air resistance are things like feathers, leaves, seeds, or small pieces of paper just to name a few. Objects when falling that can ignore air resistance are things such as objects that are heavy and compact like rocks or metal balls.
How does an open parachute increase the air resistance of a falling?
by increasing surface area

Does air resistance help a parachute slow down?
Of course it does. If there was no air resistance then the parachute would accelerate at the speed of gravity which is 9.8m/s/s. If a human were using a parachute and there was no air resistance then they would die. "Air resists the motion of objects traveling through it because its molecules collide with the molecules of the object. This resistance to the motion is beneficial because the force acts to slow down a parachute jumper's speed of fall. The jumper falls with increasing speed until the parachute is opened. The greater air resistance acting on the surface of the parachute will bring the jumper to a terminal velocity and will enable the parachutist to safely reach the ground".http://amyallen.org/mhs/applied_physics/physics_of_flight/rocket/parachutes_payloads.pdf
How do balanced and unbalanced forces relate to a parachute?
If the parachutist is just falling down vertically, he is falling because of the unbalance force. Gravity is pulling him down. Gravity is stronger than the air resistance that is "keeping him up". The two unbalanced forces: gravity & air resistance. Because they are imbalance, he is accelerating towards the Earth's surface at 9.8 meters per second.
An open parachute increases air resistance of a falling sky driver by?
Increasing his surface area
How does size affect the speed of a falling parachute?
The larger the size of the parachute the more air resistance is caused because its larger surface traps more air. Becuase there is more air resistance the larger the parachute the slower it travels to the ground. The smaller the parachute the faster it falls to the ground for the opposite reason.
What will be the effect of the acceleration due to gravity while jumping with a parachute?
The acceleration due to gravity doesn't change near the earth's surface, no matter what the cause of your fall is, or what position you assume during the fall, or what you're wearing. But a parachute sets up significant force opposite to gravity, because of air resistance. Since the acceleration is proportional to the net force, it can be reduced when there is considerable force canceling a significant fraction of the gravitational force.
What forces are acting on a skydiver?
Under free fall, the only force acting upon an object is the force of gravity. But realistically, there is also the force of friction from the air (Air Resistance) that opposes the force of gravity.
The forces acting on objects falling near the earths surface are?
Mainly gravity, and air resistance.
How do gravity and air resistance affect a falling body?
Well gravity would pull the body to the ground. The greater the surface area of the body the more air resistance there would be.
