Does the normal always equal the weight, if on a non-inclined plane?
This is just a general question that I have about normal and weight forces... I was wondering because when I'm breaking up the net forces into components, I was wondering if I should always include the normal and weight, even if its on a non-inclined plane.
Essentially, I'm asking, does the normal=weight on a non-inclined plane if the plane IS NOT frictionless? If the normal=weight, then why do I still need to include it in the sum of the components on the y-axis?

Doesn't require a solution, its just a conceptual question
