The matter that makes up an object creates it's mass.

# data[].attributes.body
Even though they’re too tiny to see, all the molecules of air in the atmosphere above your head weigh something. And the combined weight of these molecules causes a pressure pressing down on your body of 10,000 kg per square metre. This means that the mass of the air above the 0.1 square metre cross section of your body is 1,000 kg, or a tonne.

is a device used to slow down an object that is falling towards the ground. Without a parachute the gravity is more than air resistance.

# data[].attributes.body
Parachutes are a device that slows down your speed to have a safe landing.

# data[].attributes.body
The parachute works by using air resistance to slow down the object strapped to the parachute. This drastically slows the object velocity allowing it to have a safe landing.

# data[].attributes.body
The parachute is used to slow an object down that is falling. As the parachute opens, air pressure is pushing up against the surface area of the parachute, and making the object fall at a slower terminal velocity.

Pressure is force divided Area. the force of you falling divided your mass and Area.

The force on an object that resists its motion through a fluid is called drag. When the fluid is a gas like air, it is called aerodynamic drag (or air resistance). When the fluid is a liquid like water it is called hydrodynamic drag (but never "water resistance").

I believe that the more mass something has in a flat shape, the more drag it has, as air will bump into it and have a hard time getting around. Also, if the shape is in a cage-like shape, it will have an even harder time going around.

Leonardo da Vinci invented the parachute, along with Fausto Veranzio. It is used for when someone jumps from a great height and needs to slow down their speed and create more drag to land safely. Gravity pulls things down to Earth at a rate of 9.2 meters per second per second. Every second you fall, your speed increases by 9.2 meters per second. After you have reached a speed of 121 mils per hour, the air molecules can't separate fast enough beneath you, and they can't fill in fast enough above you, so more drag kicks in. Then, when you pop the parachute, there is more drag and you fall slower. A parachute is a device used to slow down falling objects by creating drag. They can be made of strong, light cloth, most commonly nylon. The surface area plus wind resistance creates drag, and that's what parachutes were made to do.

Terminal Velocity, Velocity and Drag By: Sophie H.

# data[].attributes.body
Terminal velocity is the highest velocity possible as an object falls through the air. This occurs when the drag and gravity come together.

Drag is a mechanical force that is generated by connection and contact of a solid body and a fluid.

Velocity is the speed of the object going in a certain direction.

Why Do Objects Fall at Different Speeds?

Imagine you are about to jump out of an airplane. At the last minute, you have to decide whether to take a parachute or not. What would you choose? I'm guessing that you would choose the parachute! Most people would make the same choice, because it causes you to have a much slower terminal velocity, or maximum falling speed, than if you were to fall without it. Although we all know that it is better to jump from a plane with a parachute than without it, have you ever thought about why? What factors determine the terminal velocity of a falling object like a person jumping from a plane?

Gravity

Hundreds of years ago, people thought that the mass or weight of an object was the main thing that determined how fast it would fall. This idea was put forth by the Greek philosopher Aristotle, who said that the speed of a falling object was directly proportional to how heavy it was. Although this seems reasonable at first glance, there are some big problems with this idea. Try dropping a baseball and a crumpled up piece of paper at the same time. You will see that although the baseball weighs much more, they hit the ground at about the same time.

The scientist Galileo Galilei (1564-1642) disproved this idea by showing that objects of the same size and shape but with different masses would hit the ground at the same time when dropped from the same height. Later, Isaac Newton (1643-1727) demonstrated that the Earth exerts a force on all objects near it, which causes falling objects to speed up as they fall. He called this force gravity and calculated that all objects would speed up at a rate of 9.8 m/s as they fall towards Earth. The force of gravity on every object is the product of its mass and the gravitational constant (g = 9.8 m/s^2). This force of gravity is what we know as weight. Force of gravity = mass * g.

So, when you jump out of that airplane, you immediately start speeding up at a rate of 9.8 m/s every second. If there was no air in the atmosphere, you would keep speeding up at that rate until you hit the ground. However, the air you are falling through exerts a force on you, too.

Drag Force

While it is true that the Earth exerts a gravitational force on every falling object, there is another very important force that also affects the terminal velocity of a falling object. As objects fall through air, they experience drag or air resistance forces that act upward and oppose the force of gravity. The air drag force depends on several factors, including the speed at which the object is falling (v), the surface area of the object (A), the density of the air (d) and something called the drag coefficient (C), which is determined by how aerodynamic the object is: Drag Force = 0.5 * d * v^2 * A * C. The most important factor in determining the air drag force is the velocity of the object. As it speeds up, the drag force gets bigger and bigger.

After you jump from the airplane, you start speeding up, and the faster you go, the more air drag force is exerted on you. Eventually you will be going so fast that the air drag force will be equal to the force of gravity that was causing you to speed up. At that point, you will not speed up any more but will continue to fall at the same constant velocity.

Terminal Velocity

As the object falls, the force of gravity initially causes it to continuously speed up as predicted by Isaac Newton. As it gets faster and faster, the air drag force increases until eventually, the air drag force is exactly equal to the force of gravity, and there is no net force acting on the object. If these two forces are exactly balanced, the object will no longer speed up or slow down but will continue falling at a constant velocity, called the terminal velocity.

Since the air drag force depends heavily on the size and shape of the object, objects with a large surface area (like a parachute) will have a much lower terminal velocity than objects with a smaller surface area (like a person falling from a plane). The weight of the object does affect the air drag force on the object and, therefore, its terminal velocity.

However, it is not the most important factor. This explains why a flat piece of paper will fall more slowly than the same paper after it has been crumpled into a ball. The paper weighs the same, but the air drag forces have decreased because its surface area and drag coefficient have changed. This causes the crumpled paper to have a higher terminal velocity than the flat paper. This also explains why a parachute can lower your terminal velocity when you jump from an airplane. The parachute has a very large surface area and drag coefficient and a relatively small mass, so it experiences much higher air drag forces than you would without a parachute.

Solid matter falls through the air at 9.8 meters per second every second. (increases by 9.8 meters every second) This shows how quickly you are falling -terminal velocity-

Resistance: The refusal to let something by, such as matter. You body, falling through the air, creates resistance and blockage as you fall. Also known as "drag"

The parachute also creates blockage and starts slowing stuff down.

From what I have found drag means to pull down with force, or in other words pull, resistance, or tug.

I read some where that air has weight, right? I think it would be pressing on you the whole time you were falling. So maybe air mass has something to do with the terminal velocity of a falling object.

Hello, you can copy this link into a google search to find an article by NASA about Velocity during recovery such as a parachute example.

# data[].attributes.attachment_link.readable_text
The forces on a model rocket change dramatically in both magnitude and direction throughout a typical flight. This figure shows the velocity of a rocket during the recovery portion of the flight. At the end of the powered portion of the flight, the model rocket uses up all its fuel, the engine goes out and the thrust goes to zero. The rocket then coasts upward until the velocity goes to zero and the maximum altitude is reached. Because weight is still acting on the rocket, it immediately begins to fall back to earth. To slow the descent, an explosive charge is used to deploy a parachute. As the rocket falls, only two forces are acting on the rocket, the weight of the rocket and the aerodynamic drag on the parachute.

The weight (W) is always directed towards the center of the earth. By definition, the aerodynamic drag (D) is opposed to the flight direction. As the rocket descends, the drag and the weight are opposing forces. The vertical force (Fv) is the drag minus the weight.

Fv = D - W

The drag depends on the square of the velocity,. The rocket is falling at a high rate of speed when the parachute is deployed so the drag is high. The point is quickly reached where the drag is equal and opposite to the weight. At this point, there is no net external force on the rocket and from Newton's first law of motion the acceleration then becomes zero and the rocket falls at a constant terminal velocity.

We can determine the magnitude of the terminal velocity. As discussed above, the net vertical force on the rocket is zero and the drag is then equal to the weight. The drag equation states that the drag (D) is equal to some drag coefficient (Cd) times half of the air density (r) times the square of the velocity (V) times the reference area (A).

D = Cd * .5 * r * V^2 * A

We can equate this to the weight and solve for the velocity.

V = sqrt ( (2 * W) / (Cd * r * A) )

The terminal velocity depends on the weight, the drag coefficient, the air density and the reference area. The air density has a typical value of 1.229 kg/cu m. Typical values of drag coefficient for a parachute is about 1.75, compared to 0.75 for a typical model rocket. The higher drag coefficient produces a lower terminal velocity. The reference area is the large large cross-sectional area of the parachute which also produces a low terminal velocity. Compared to the descending rocket, the descent under parachute is slow and the rocket can survive the impact with the ground and fly again.
