Friction & Inclined Plane Calculator

For a block on a slope, finds the normal force, the gravity component down the slope, the maximum static friction, whether the block slides, and its acceleration if it does.

Notes

  • The block starts to slide once the slope's pull mg·sinθ exceeds the maximum static friction μs·mg·cosθ.
  • That threshold happens at the angle where tanθ = μs, independent of the mass.
