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)
