When an object moves on an inclined surface it has two component of forces.

Let A be angle which inclined surface makes with ground.

So one force is along the movement of body and other is in opposite direction of normal force Something like thisin image

The F is force applied to move up the object.

Force of friction would be in direction of mgsinA.

And it would be umgcosA ,where u is coefficient of friction so net force along movement will be :F-(mgsinA+umgcosA)
