Classical mechanics discusses the behaviour of macroscopic bodies under the influence of forces (without necessarily specifying the origin of these forces). If it's possible, USE MORE SPECIFIC TAGS like [newtonian-mechanics], [lagrangian-formalism], and [hamiltonian-formalism].

When two balls collide with each other (not head on), will linear momentum still be conserve...
Realize that friction is not a external force for the system of two bodies.
Say friction imparts a impulse J on one ball then it will impart -J impulse on the other ball yes the momentum will be conse …

Force from time and velocity
Impulse $\vec J$ imparted by force $\vec F$ will be equal to the change in momentum $\Delta \vec p$. $d\vec J=\vec Fdt$. Force being constant $\vec J=\vec Ft$. $$\Delta \vec p=m\vec v=\vec J$$ which …
