Resolving weight on a slope
g = 9.8 m s−2 · static and kinetic μ taken as equal · arrows drawn to scale within each diagram

Forces (N)
| Weight W = mg | |
| Along the slope, mg sinθ | |
| Into the slope, mg cosθ | |
| Normal force N | |
| Friction f | |

Move a slider to begin.
- Acceleration does not depend on mass
- Found the angle where it starts to slide
- Frictionless: a = g sin 30°
