About Inclined Plane Calculator
Inclined Plane Calculator is a free online calculator that gives you an instant, accurate result as you type. Calculate the force needed to hold an object on a frictionless inclined plane, plus the normal force, from its mass and the slope angle.
The calculation uses the standard formula F = m × g × sin(θ) and updates live with every change to the inputs. Everything runs client-side in your browser — fast, private, and free to use as often as you like.
On a slope the weight splits into two components: mg·sin(θ) pulling the object down the ramp and mg·cos(θ) pressing it into the surface.
