The interactions in physics

How is it possible that such small elements of matter can give rise to so many different phenomena and, above all, can form bodies that are extremely larger than themselves,
such as gigantic planets and clusters of stars?
This question is answered in the fact that, as was previously stated, all particles have properties through which they interact.
This didactic unit allows to verify that there are no single forces as all the interactions satisfy the 3rd principle of dynamics.
