Not the weight explicitly, but the ballistic coefficient, which is m/CdA. Cd is the drag coefficient and A is the area. Which area depends on how you defined Cd. The downward force on an object is mg. The resisting force is CdA (1/2 rho V*V). Rho is the density of the fluid. At the terminal velocity, the two forces are equal, so Vterminal = sqrt(2mg/rho Cd A) or, if you separate the environment from the falling object Vterminal = sqrt (2*g/rho) sqrt(m/CdA) So as long as m/CdA stays the same, the terminal velocity should stay the same. Since mass usually varies with the cube of the linear dimension, while the area varies with the squre, larger things tend to have higher terminal velocities because m/A increases with the size of the object. Mice and elephants have similar densities and drag coefficients, but the m/A of the elephant is much larger just because it's bigger, so an elephant dropped off the Leaning Tower of Pisa will fall faster than a similarly-mistreated mouse. So Galileo was wrong while being right.
What else can I help you with?
What happens when the amount of drag becomes larger than the amount of thrust?
This state is known as terminal velocity. In it's current shape, an object as described cannot travel any faster. The force of gravity is constant where as the force of air resistance increases with velocity so it takes time for an object to reach its terminal velocity.
What force would change if a parachutist opens the parachute during the fall What will happen to the net force and acceleration over time after that?
When the parachutist opens the parachute, the air resistance force will increase. This will reduce the net force acting on the parachutist, causing a decrease in acceleration over time. As the parachute slows the descent, the net force continues to decrease until the parachutist reaches a terminal velocity.

When you change the amount of a substance the time it takes to reach the boiling point then what happens?
The lower the amount of substance, the faster it reaches the boiling point. The more the amount of substance, the longer it takes to reach the boiling point. Hope that this is what you wanted to know! :)
How far do you have to fall to get to terminal velocity?
Terminal velocity is the constant speed that an object reaches when the force of gravity pulling it down is balanced by the force of air resistance pushing up on it. The actual distance required to reach terminal velocity varies depending on the object's mass, shape, and other factors. But in general, it takes around 1,500 feet for a skydiver to reach terminal velocity.
Why does an object with a large surface area reach terminal velocity before an object with a small surface area?
An object with a large surface area experiences more air resistance, which increases as the object accelerates. This causes the object to reach terminal velocity quicker compared to an object with a smaller surface area, which experiences less air resistance and takes longer to reach terminal velocity.
How many feet does it take to reach terminal velosity?
Terminal velocity is the constant speed an object reaches in free fall when the force of gravity is balanced by air resistance. The distance it takes to reach terminal velocity depends on the object's weight, shape, and air density. Generally, it can take a few thousand feet for a skydiver to reach terminal velocity.
How does concentration of a fluid affect the motion of falling objects?
The higher the concentration of a fluid, the longer the time it takes for an object to fall and therefore the smaller the terminal velocity.
What happens before terminal velocity takes place?
Before terminal velocity is reached, an object will be accelerating due to the force of gravity. As the object accelerates, air resistance (drag) will increase, which will gradually counteract the force of gravity until the two forces are equal and the object reaches terminal velocity.
What is the greatest velocity a fallen object reaches?
If air resistance is significant, after falling for a while the air resistance will be as strong as the force of gravity; the two forces will be in equilibrium, and the object won't accelerate any more. This velocity is called "terminal velocity". The amount of this terminal velocity, and the time it takes to approach the terminal velocity, depends on the specific object that is falling.
What is the terminal velocity of a human?
Roughly 120 mph flat and stable. Head-down is much faster, but is not stable (it takes active control). Terminal velocity is when the gravity force upon an object is equal to that of the wind resistance.
Does terminal speed and terminal velocity are the same?
Yes, but only in free-fall. If I'm driving at 60 mph, I have a constant velocity, but it's not my "terminal velocity" in the sense that there is no limit to my acceleration caused by air friction. But yes, an object in free-fall reaches its terminal velocity when its velocity stops increasing (acceleration=0).
When you skydive Why don't you hit maximum speed before you hit the ground?
The maximum speed you can reach is also known as terminal velocity and this is the speed at which your mass is resisted by the air. Typically in a belly to earth body position, this is around 120mph. It takes around 10 seconds to reach this speed. The minimum exit height is 2500ft and would not reach this terminal velocity before they need to deploy their parachute. Most skydivers jump from a lot higher - between 10,000ft and 15,000ft. This gives them a freefall time of over 45 seconds and therefore they reach terminal velocity. Once the parachute is open, the decent rate is less than 10mph, so no you do not hit the ground at maximum speed in answer to your question.
What is the acceleration of a rain drop that falls at a constant velocity?
This is not a simple question and not enough information is provided to answer it. Among other things it depends upon the time it takes to reach terminal velocity and the terminal velocity depends on the various drag forces operating which in turn will depend on other variables such as initial height, wind speed, temperature, humidity, etc. You could calculate the velocity of any object falling in a vacuum if the acceleration due to gravitational force remains constant throughout the fall. v=v0+at where vo=initial velocity (probably zero if the object is initially at rest), a is the acceleration due to gravity (9.8m/s2) at or near the surface of the earth, and t is the time of fall.
A 180 lb person jumps from 16 story building how fast do they fall?
32 feet per second per second is the standard acceleration.As the object accelerates (usually downwards due to gravity), the drag force acting on the object increases. At a particular speed, the drag force produced will be equal to the downward force, mostly the weight (mg), of the object. Eventually, it plummets at a constant speed called terminal velocity (also called settling velocity). Terminal velocity varies directly with the ratio of drag to weight. More drag means a lower terminal velocity, while increased weight means a higher terminal velocity. An object moving downward at greater than terminal velocity (for example because it was affected by a force downward or it fell from a thinner part of the atmosphere or it changed shape) will slow until it reaches the terminal velocity. For example, the terminal velocity of a skydiver in a free-fall position with a semi-closed parachute is about 195 km/h (120 mph or 55m/s).[1] This velocity is the asymptotic limiting value of the acceleration process, since the effective forces on the body more and more closely balance each other as the terminal velocity is approached. In this example, a speed of 50% of terminal velocity is reached after only about 3 seconds, while it takes 8 seconds to reach 90%, 15 seconds to reach 99% and so on. Higher speeds can be attained if the skydiver pulls in his limbs (see also freeflying). In this case, the terminal velocity increases to about 320 km/h (200 mph or 89 m/s),[1] which is also the maximum speed of the peregrine falcon diving on its prey.[2] Competition speed skydivers fly in the head down position reaching even higher speeds. The current world record is 614 mph (988 km/h) by Joseph Kittinger, set at high altitude where the lesser density of the atmosphere decreased drag.[1] An object falling on Earth will fall 9.80 meters per second faster every second (9.8 m/s²). The reason an object reaches a terminal velocity is that the drag force resisting motion is directly proportional to the square of its speed. At low speeds, the drag is much less than the gravitational force and so the object accelerates. As it accelerates, the drag increases, until it equals the weight. Drag also depends on the projected area. This is why things with a large projected area, such as parachutes, have a lower terminal velocity than small objects such as cannon balls.
What is the acceleration experienced by a car that takes 10s to reach 27 ms from rest?
The acceleration experienced by the car would be 2.7 m/s². This can be calculated using the formula: acceleration = (final velocity - initial velocity) / time.
