How to calculate acceleration due to gravity in a 3D $N$-Body system?
How do you calculate acceleration due to gravity for objects in 3D space?
My current understanding for the force due to gravity on object $i$ from object $j$ is
$$\mathbf{F}_g=(\mathbf{r}_j-\mathbf{r}...

Method to build a polyhedral die with given probabilities [closed]
Let's define a die as a polyhedron that, if rolled over a perfect horizontal plane, ends up being in a physically stable unambiguous state labelled $n$. The die has $N$ states. Each state $n$ has a ...

MEMS gyro measured angular velocity vector
Notations I use:
Consider a world frame $\{O_0, \vec{i}_0, \vec{j}_0, \vec{k}_0\}$ coordinate system and a rigid body $B$ with a coordinate system $\{O_1, \vec{i}_1, \vec{j}_1, \vec{k}_1\}$ attached ...

How to simulate gravitational interaction of bodies in space?
I want to try simulating some bodies in space using the basic formulas I learned in my college mechanics class.
So I know Newton's Law and some basic mechanics equations:
$\vec{F} = G\frac{m_1m_2}{r^...
