What is the difference between net force and resultant force (urgent!)?
It is the resultant force because you calculate the resulting vector sum using the Pythagorean Theorem. It may or may not be a net force; it wouldn’t be if there was another force of equal magnitude in the opposite direction. A net force is the force you’re left with when you add up all the force vectors; if they add up to zero, there is no net force.
