Terminal velocity Definition and 224 Threads

Im doing a coursework based on the viscosity of Godlen syrup at the momement. I have got my results and have plotted a Distance Time graph for each of my 4 different ball bearings that were dropped through syrup. Now my first question is do i have to join the points up with a curve and then...

I am working on a problem involving spray dryers. The material to be dryed would be injected through a centrifugal disk with spherical multiple openings of about 0.5 mm in diameter. Hot air would be blown from the dryer's bottom part. I was wondering how can I approach the problem to find out...

Given: wooden sphere gravity = 9.8 m/s^2 radius of sphere = .18 m density of sphere = 801 kg/m^3 Drag coefficient = 0.5 I found out the velocity of the wooden ball to be 3.07 m/s (please confirm). Now it has to go through the air that has density of 1.2 kg/m^3. What would be the speed...

I know terminal velocity is when the upward force is equal to the gravitational pull, but is that only in free fall? Would something with air resistance like an arrow shot from a bow be affected by terminal velocity? I'm not to clear on how it works...

hi again, I'm pretty sure I understand the concept of terminal velocity in that there is an upper limit to the speed of a falling body. How do you calculate the terminal velocity of an equation? For example: v = \frac {g} {\beta}( e^{- \beta t} - 1) v represents velocity

Im fairly ignorant on the theory of terminal velocity. It says that matter has a maximum speed in a certain direction. Is it possible that another factor could be the distance to the centre of gravity, which ever way it may be attracted? If a marble is dropped at 999m (just work with...

Hi I doing a coursework on finding the terminal velocity of a steel ball in a liquid at different temperatures How is my graph suppose to like? My two variables are temperature and terminal velocity (i got my terminal velocity from speed = distance / time) And if possible, if you know it...

A projectile is ejected into an experimental fluid at time t = 0. The initial speed is v0 and the angle to the horizontal is theta. The drag in the projectile results in an acceleration term a_d=-kv, where k is a constant and v is the velocity of the projectile. Determine the x- and...

Hi. I could use some help from someone who is pretty good at physics. Me and a few others are doing a project (that has nothing to do with physics) and we need to know the velocity of a person at the time of impact who fell from 100 meters. We figured out that it would be about 100miles per...

Hi, I have a theory about light: could our observations of light always traveling at 300 000 km/s be explained as the terminal velocity of light? When an object falls through the atmosphere it will eventually stop accelerating because the pressure of the atmosphere equals the pull of...

If a body is in freefall and has reached its terminal velocity say 56 metres/s, its acceleration is zero, how do you work out with what force it would hit the ground

hey how do you find terminal velocity? let say if you need to find the terminal veolcity of a ping pong ball? anyone has any ideas? what kind of experiment can i conduct?

okay so i posted earlier (while back) regarding terminal velocity. I have a parachute experiment set up, but i cannot find a way to calculate terminal velocity. does anyone out there have a formula i can use to find terminal velocity if all i got is a good old fashioned pencil, paper and...

looking back at a problem that puzzled the heck out of me. integrate this: dv/(v-vt) = -k/m (dt). The book says you get: ln ( (vt-v)/Vt ) = -k/m t the -k/mt part is fine, because you integrate from 0 to t. The ln part is tricky though. When I integrate, I get ln(v-vt), vt is...

Hi Guys, I am doing a physics ee on the terminal velocity. So I am going to drop a spherical object into a graduating cylinder which has a really wide diameter and is relatively tall. Now the problem is that I have to measure the time taken between a fixed vertical distance. I have to measure...

Hey ppl, just a quick question.. You have a 10 g ping pong ball with a diameter of 3.5 cm... a)The ball is shot straight up at twice its terminal speed. What is it’s initial acceleration? i know D=W at terminal speed but when u double it do you just assume D=4D and if you do how come...

This is my first time posting here but i need some serious help. I'm in the process of doing a physics project right now, and I decided to relate the surface area of an object to its terminal velocity. I know how I am going to set up this experiment using coffee filters and string and a set...

if we made a vacuum tube ten thousand feet high, and dropped a million tonne weight into it, it would have no terminal velocity right? how fast would it hit the ground? armageddon? :P

i'm looking for an equation to calculate terminal velocity. Does anyone know it? and can u please post in here please. :smile:

if a bullet is shot up in the air will it return to the ground as fast as it was shot up or will air resistance slow it down enough to not cause as much damage?

How would you calculate the terminal velocity of a massive object falling through a bottomless vacuum? As nothing can go faster than the speed of light the object must have a terminal velocity also due to E=mc^2, and A=F/M... I am just wondering if you can calculate the terminal velocity...

Not quite the right term as this is a question about acceleration and transfer of energy. If You hit a cue ball slowly, it will continue to roll after it hits the billiard ball. However if you hit the cue ball quickly it will come to a complete stop. if you accelerate from 0 to 100 in 5...

Any help will be greatly appreciated. Superwoman is hovering above the ground when a person free-falling goes by her at a terminal veloctiy of 140 km/h (39m/s). Unfortunately, the parachute doesn't open. Fortunately, Superwomanis around. If it takes her 1.9s to realize the person is in...

What would happen if you hit a body of water( say an ocean) at the terminal velocity of a person of avg proportions without any special clothing on..just like a jumpsuit? (how would it change for Feet first/head first/belly flop/at an angle etc?)
