Homework Statement
Find the force and acceleration of the block down the inclined plane
Homework Equations
F = ma
The Attempt at a Solution
We have two unknowns in F = ma
I know there is the gravitational force going straight down, and there is the normal force that is perpendicular to the incline.
What I don't know if is if the force of gravity acting on the block and the normal force are active/reactive for pairs (do they cancel each other out like an object would at rest?) because I'm told every object has at the least two forces acting on it (the force pairs according to Newton's 3rd law).
So I know the force pulling down on the object is gravity, but what other forces are there that I can calculate the force of the object sliding down the incline?
