Inclined Plane Calculator
Force from Mass and Angle
F = m × g × sin(θ)
Force from Ramp Dimensions
MA = ramp length / ramp height
Formula
F = mg × sin(θ) | MA = length / height
Frequently Asked Questions
How do I calculate force on an inclined plane?
The force needed to push an object up an incline (ignoring friction) is F = mg × sin(θ), where m is mass, g is gravity (9.81 m/s²), and θ is the angle. The mechanical advantage is the ramp length divided by the height.
What is the mechanical advantage of a ramp?
MA = ramp length / ramp height. A 10-meter ramp rising 2 meters has MA = 5. This means you need only 1/5 the force compared to lifting straight up, but you must push the object 5 times farther.
