Explanation

Internal forces (forces between particles of the same system) act in equal and opposite directions (Newton’s Third Law), hence they cancel each other out.
As a result, they do not affect the conservation of linear momentum or energy in the whole system.
Only external forces can alter conservation laws for the system.
