3n a solid, molecules are packed together, and it keeps its shape. Matter is the "stuff" of the universe, the atoms, molecules and ions that make up all physical substances. ... In a solid, these particles are packed closely together and are not free to move about within the substance.

4.sliding frictipn

5.This maximum force is known as traction. The force of friction is always exerted in a direction that opposes movement (for kinetic friction) or potential movement (for static friction) between the two surfaces.
