Hello, With Simulink, how can I modelize a point in the space and get back (in outputs of the block), the 3 coordinates, x, y, z of this point. Thanks for answers

I would start with good old Newton's 2nd Law: F = m*a
For each coordinate (X, Y, and Z), you can implement this relationship with two Integrator blocks; one that integrates from acceleration to speed, and one right after it which integrates from speed to position.
What you put into the input (the forces, or the "F" part) is up to you.
For reference, I would start by looking at the Bouncing Ball example for a few different ways you can model the 1-D system. Then, you can extend that to 3-D.

Well, the gravity could be replaced with any other forces... whether they be zero, or components (sine-cosine) of gravity, or anything else. The left side of the first integrator is the sum of all input forces to the system.
