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° direction, what are the equations of the ball in x and y?
mx" = -Fx = -Ffric cos (alfa)
my" = -Fy - -Ffric sin(alfa)
It seems that this does not works since the friction force is a nonconservative force ... Is Lagrange method still valid?
regards,
