Inclined Plane Calculator Inclined Plane Calculator Analyze forces acting on an object resting or sliding on a slope. Mass (kg) Angle of Incline 30° Kinetic Friction (μk) Applied Force up incline (N) Calculate Forces Gravity Parallel (mg·sinθ)– Gravity Perp (mg·cosθ)– Normal Force (N)– Friction Force (fk)– Net Force along incline– Acceleration (m/s²)–
