Can external forces be considered as the forces acting from a distance and internal forces are the contact forces(except frictional forces)?
since we know that according to Newton 3rd law every object making a force on a second object the second object will make the same force on the first object but in opposite direction.
But in this case if we take for example a certain object if all the forces acting on this object are contact forces(except frictional) then the net force acting on this object is the sum of the internal forces.
