And when it is very inconvenient to consider it 1D, is it still correct to split the forces into Fx and Fy?

friction as a nonconservative force I was wondering, can the friction force be split up? Suppose you have a friction force working under an angle alpha, can you just say Fx = Ffric*cos(alfa), Fy = Ffric*sin(alfa) Suppose you're working in a flat horizontal plane, and you launch a ball in 45°...
