Thanks for your answer! But, you're indeed not correct this time. It's my fault that I didn't manage to clarify my problem very well, but actually, you don't have only one free parameter in the input. You have two of them. One of them is the "well known" extension of the leg, while the other one...

Well, I'm trying to find the answers to the problems mentioned in my previous post, but so far I've been unsuccessful. If anyone could find them sooner than me, I'd be thankful.

Thanks for your answer! This is actually correct. I even managed to figure this out myself, that's why I wrote in my first post, that I thought I had solved it. But I figured, that in reality, this is unfortunately not enough. Assuming that the leg is massless is probably fine, the problem is...

It is an "internal motor". It actually is literally a leg, that's stretching by rotating it's joints. So it's "pushing" the ground, applying some force to it, and therefore keeping the upper body at the same height.

Hi everybody! I'm struggling with a physics problem I though I had solved, but as it is turning out recently, I probably hadn't. The problem might actually be pretty easy, just me being unable to solve properly. All of you are familiar with inverted pendulum. Now, imagine an inverted pendulum...

Rather draw a velocity vs. time graph and I'm sure you'll understand.

I'm not sure if I understand you, but what I was basically trying to say was that the average velocity has it's use in reality when you want to calculate (or more precisely: measure) the velocity of a moving object. Example: Assume you have a video record of a moving car. Now you want to know...

Average velocity is not very useful in theory, but in reality it is. How do you measure the velocity of an object? Well, you can't really measure it's actual velocity at any precise point of time. You can only measure how long it took for it to travel some short distance. Then you calculate the...

Oh, the whole problem was, that I was calculating with the absolute linear velocity of a body instead of relative to the velocity of the center of mass. So yeah, it was not intended :). Thank you very much for your help and patience!

I'm programming it in Java and it will be for Windows, Mac OS and Linux. I'm using the LibGDX library for it, so it may be ported to Android and iOS later.

Ok, here's the pseudocode of what I've got (I can calculate the center of mass no problem): [FONT=Courier New]totalInertia = 0; totalAngMomentum = 0; for (body: bodies) { distance = dst(body.getPosition(), centerOfMass); inertia = body.getInertia() + body.getMass() * distance^2...

I don't know what that means, but yeah, exactly that except for the teleporting :). The game is not much to show yet, but hopefully will be in a short time. If you want to see some updates coming you can follow me on twitter @faiface.

Hello, this is a question regarding planar physics. Suppose we have multiple bodies. We can ignore their individual shape and angular speed. So every body is represented by it's position, mass and moment of inertia about it's center of mass. Now my question is, how to calculate the moment of...

It's more similar to the Xiao Xiao "movie". If you don't what that is, just search it on youtube. In my game you actually play as a stickman that is fully physically simulated (no animation involved, not even keyframe animation). Now this stickman has bones and muscles and he's got to operate...

Hi, my name's faiface, and I'm working on a fully physics based platforming game. That means, that your character is a ragdoll. But not a regular ragdoll. It's a ragdoll that can maintain balance, stand, walk, run, jump, climb. Well, not everything mentioned yet, but it's getting there...
