G-forces Definition and 22 Threads

Hello everyone, I hope you are all great. I am writing down to all of you concerning a problem of mine. I am struggling to generate a trackmap based on Speed (m/s) and G-Forces on excel. I followed a topic created 12 years ago but unfortunately it is closed ...

There's a game that I like to play that has planes and code, and collects things like angle of attack and speed. I was wondering how it'd be possible to get the rate of g-forces experienced within a climbing turn; I already understand from this thread...

I've been to the amusement park recently, and one day I decided to use an app (Physics Toolbox), to collect some data. I downloaded the data, and it gave it to me in a .csv format. This table of data showed that there were x,y and z values for G-Force. I don't understand how G-Force has x,y...

Hello Folks I'd like to know if anyone of you guys know how to calculate the gforces in a glider (in this case helicopter) during maximum performance acceleration? Tonight I had a very serious discousion with a relative of mine who doubt that it's possible to accelerate from 0 to 140 kts within...

Hi all, I am currently reading 'The Science of Interstellar' by Kip Thorne. Kip says that cooper could navigate around the Gagantua system using Gravitational Slingshots with Intermediate-Mass-Black-Holes. However these interactions would accelerate/decelerate the ranger by up to 22% of the...

I hope this is the right place for this... Question #1. How much can the human body stand multiple rapid G-force changes. Like let's say I made a vehicle that you could make sure all your body parts were 100% secured and it could move freely in space in any direction what would be the result of...

Hi all, Does anyone know what physics limits human tolerance to extreme g-forces? I know the average human can take g-forces 5-7 g, and a fighter pilot, with training and a G-suit can maybe get up to 12 g. And people can survive g-forces higher than this for a very short time. I know all the...

Homework Statement I have constructed a small scale roller coaster for my physics class. I was given the task of finding a track design with a safe and enjoyable ride. For times sake I plan to simply calculate the changes in g-force. I am using a hotwheels car and plastic track. I simply need...

Homework Statement The PDF graph shows the g-force values of a roller coaster at specific times during the ride. The normal g-force value during this assignment is -1 because the acceleration due to gravity on Earth is -10 m/s^2. We have to assign each time value from the PDF graph to...

Having an infuriating time trying to explain physics to co works. The debate is as follows: to get to Pluto in a quick time, say less than a year, you would have to travel extremely fast. If it were possible to reach such a speed via rockets/ion drive the human body would be crushed under the...

Hi all, I was working on same basic physics with calculate the apparent weight of a pilot in a turn. Let's have the plane be oriented such that the cockpit faces the sky, the belly faces the ground to start off with. Now, "Positive G-forces" are for a plane that begins to climb, or to put...

Hi, I'm trying to figure out the G-Forces a rider will experience whilst riding an amusement park ride. The track is 200m long and the 'pod' (What the rider is in) accelerates uniformly at a rate I found to be 5.1m/s2. So, to calculate the G-Force, I planned to use the formula g's = a /...

Hi, nice forum. I was thinking how I would go about proving with an example, that negative Gs are occurring? Homework Statement Say a stunt pilot is doing a maneuver that will expose him to negative Gs. It could look like this...

I have a question. Would it be possible to calculate the velocity of a thrill ride at any given time, given the rate of change in g-forces and the velocity of the ride at the start (or if there's a hill at the start, the velocity of the car going uphill)?

Homework Statement A rollercoaster car is going over a hill, with a person sitting with -no- restraints. The velocity of the car and radius of the hill are such that the centripetal acceleration of the cart is 15 m/s^2. What is the relative g environment (for the rider) and how many g's does...

Are G-forces smaller when traveling in space?

proper acceleration is the acceleration actually felt/experienced by an accelerating body. the integral of this gives the proper velocity. this makes intuitive sense. but the derivation of the formula for proper acceleration doesn't make intuitive sense to me. I'm very confused about how one...

Hi, I need a little help with my understanding of g-forces. From what I can gather, this "force" is the acceleration experienced by the object expressed as a multiple of g (the usual acceleration due to gravity). What has confused me, though, is the Wikipedia page, which says that "A...

As the tile says, anyone's got an idea what the g-forces might be at the boundary of a black hole's event horizon? I got a formula to calculate the event horizon radius but not the the gravitational forces. Equivalence to Earth G's would be nice or in m/s2 = meter per second squared! Is it...

Im having a bit of trouble understanding g-forces. I get that you divide the forces acting upon an object by 9.8 to obtain the number of g's but does that include forces like force normal? I am also having trouble applying them in situations when acceleration is in different directions such as...

Hello everyone. I know this may be a simple problem for some, however I am having a hard time figuring it out. I need to figure out how many g-forces are experienced when dropping a 210 pound (95.2kg) object a distance of 1.5 feet. Thus I can figure out how much that object "weighed" at the...

I was watching Star Wars and started to wonder. If a man were flying a spacecraft in space, would he be able to turn quickly and speed up quickly? Or would there still be a G force like in jets on earth? Kind of hard for me to explain it. I know that the jets now days can turn faster than the...
