    Collision Response
AI Thread Summary
The discussion centers on simulating the physics of colliding objects in a game, specifically focusing on calculating new speeds and rotations after a collision. The user, Nils, seeks guidance on the necessary formulas and resources to understand the physics involved, mentioning familiarity with concepts like mass, speed, and rotation. A response highlights the importance of conservation of linear momentum and provides a link to a resource on the topic. Additionally, another user offers to share a MATLAB program that models a rotating object collision, which could serve as a practical starting point for Nils, despite its limitations in dimensions and friction effects.
Nils Schneider
Hello users,

I'm working on a game at the moment which needs some physics. I try to simulate two objects at the moment that are colliding in the air. I know the mass of both objects, the mass center point, the collision point, their current rotation and their current speed etc, all I need ( I think ).
But I don't know how to figure out what will be the new speeds of both objects and their new rotations.
Does someone know a good link where I can read something about it. I think my knowledge of math should be good enough to program a solution for it if I only know the right formulas. I've read already something about F, a, v, m and all that stuff and I know the basics, but I don't know where to use which formula. Any hints would be great.

Thanks!

Nils

Hey Nils,

I had to write a program which modeled the collision of a rotating 'barbell' and a surface.

If you know how to speak MATLAB, I'll be more than happy to send it to you. It's only 2D, and it doesn't include any friction effects, but it could help get you started.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
