Angle of repose

Tilt a rough plane until the block begins to slide. The critical angle reveals μs.

Open the simulation

What to notice

Below θc static friction adjusts to hold the block; above it, kinetic friction cannot stop the slide.

Key relation

tan θc = μs ; a = g(sinθ − μk cosθ)

Try this

Set μs = 0.58 and find the angle where sliding begins.

What you can change

• Static friction μs: 0.1 to 1.2
• Plane angle θ: 0 to 60 °
