Which is greater - the terminal velocity of a small blood droplet or the terminal velocity of a large blood droplet?
The small blood droplet would have a greater terminal velocity. The smaller droplet has a smaller surface area, thus suffers less air resistance.
How does a parachute reduce the terminal velocity of a person falling through the air?
The parachute increase the surface area and so therefore increase air resistance, slowing the person down, and reducing terminal velocity.
What factors affect terminal velocity?
Factors that affect terminal velocity · Mass An increased mass will increase the terminal velocity and make the falling object reach the ground quicker. · Surface Area If the surface area of an object is increased then its terminal velocity will decrease. This is because it will have larger air resistance acting upwards on the object; therefore the object will travel at a slower rate. · Shape Shape does affect the terminal velocity of a falling object or for example a parachutist; if two people of the same weight but in different body positions (one flat stable and one head down in a dive) are free falling on a skydive, they will fall at different rates . The flat stable diver will travel at a slower rate than the head down diver, and will have a slower terminal velocity. This of course is because of surface area and the air resistance working against area of the object (or sky diver) that is exposed.
How parachutes decrease terminal velocity?
There is more surface area for the air particles to hit making the weight to air resistance ratio unbalanced.
How many feet does it take to reach terminal velosity?
1) Terminal velocity is never quite reached; a falling object will get closer and closer to terminal velocity. You can put some arbitrary limit, for which you can say that "for all intents and purposes, terminal velocity has been reached", for example, 95%, or 99%, of terminal velocity. 2) The actual terminal velocity varies for different objects. A feather will approach its terminal velocity almost instantly; a heavy object, without much surface area (for example, a steel ball) will have to fall more seconds (and more meters or feet), before it is anywhere close its terminal velocity.
What veritables determine how fast an object will be moving when it reaches terminal velocity?
The surface area is the variable to determine how fast an object will be moving when it reaches terminal velocity.
What is the airspeed in MPH of terminal velocity?
It depends on the surface area, shape, and the weight of an object, among other things. It also depends on altitude.

Why do some objects fall through the air at a diffrent rate then others?
The terminal velocity will depend on the mass (greater mass = more terminal velocity) and on the air resistance, which depends greatly on the surface are (more surface area = less terminal velocity). 2nd Answer: I believe that objects of differing mass fall at the same rate if you exclude air resistance. I remember the penny and the feather in an evacuated cylinder hitting the cylinder bottom at exactly the same time.
What is the name of the greatest velocity a falling object can reach?
Terminal velocity. It occurs when the force of gravity is equal to the force applied by air resistance in the opposite direction. With equal and opposite forces the object can not accelerate and falls at a constant speed. Every object has a different terminal velocity and depending on the surface area, can also be manipulated
Are you in free fall if you use a parachute?
interesting: in effect you are, because you have reached the terminal velocity for your surface area, which happens to be very large! if wrong, someone please correct me.
Does rain drop fall with constant velocity?
No it does not, as a raindrop falls to earth it will gradually slow due to the changing terminal velocity. As a raindrop falls, water will evaporate from it causing the mass to decrease faster than the size and surface area. this will leave the raindrop with a higher surface area to mass ratio. Since air resistance is related to surface area and mass, the smaller raindrop will have more air resistance for its mass and will fall slower.
Does an object that is in free fall seems to be slowed or speeded by air resistance?
this is a complicated question! initially, air resistance slows objects in free fall down. until a point in which the object reachs terminal velocity! Terminal velocity is when the object is at its maximum speed free falling the air resistance is equal to the acceleration so the object now neither speeds or slows down. also, the bigger the surface area the object has, the higher the air resistance will be, lowering the terminal velocity of the object.
