Inclined Plane & Forces Simulator
Explore forces on an inclined plane. See the free body diagram, force components, friction, and whether the block will slide or remain in equilibrium.

The Physics Behind It
Force Equations
- Component along ramp: F‖ = mg sinθ
- Normal force: N = mg cosθ
- Friction force: f = μN = μmg cosθ
- Net acceleration: a = g(sinθ − μcosθ)
- Slides when: tanθ > μ
Key Concepts
- Resolving forces: weight is decomposed into components parallel and perpendicular to the surface
- Normal force is the surface's push-back, always perpendicular to the ramp
- Static friction prevents motion up to a maximum value μN; beyond that the block accelerates
- The critical angle where tanθ = μ is the steepest angle for static equilibrium
