What affects sliding friction
Sliding friction depends on normal force and roughness, not area. This “What affects sliding friction” page is an MVP interactive sketch — formulas, controls, and live readouts in the browser; a fuller bench may follow.

How to use
- Adjust parameters in the left panel.
- Use play / pause and speed controls.
- Match right-side readouts to the formulas.
- Reset to return to the initial state.
Applications
- What affects sliding friction: Sliding friction depends on normal force and roughness, not area.

FAQ
What does MVP mean on this page?
An interactive sketch with formulas and parameters. Polished Ready labs are the full bench experience.
What does the “What affects sliding friction” lab practice?
Tune parameters and match readouts to the “What affects sliding friction” relations — useful for prep and demos.
Is force always along velocity?
No. Net force aligns with acceleration; velocity can point elsewhere.
How do graphs show uniform vs accelerated motion?
Uniform: constant x–t slope. Constant a: straight v–t with slope a.
