Conveyor belt model
Relative velocity v_rel = v − u sets friction direction; co-speed criterion μ ≥ tanθ; heat Q = f·|Δs_rel|; energy conservation W = ΔEk + ΔEp + Q.
Newton’s laws (senior)Hooke, friction, force composition, apparent weight.

Key formulas
v_{\text{rel}}=v-uf_{\text{滑}}=\mu mgQ=f\cdot\Delta s_{\text{rel}}
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

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 “Conveyor belt model” lab practice?
Tune parameters and match readouts to the “Conveyor belt model” relations — useful for prep and demos.
Self-study or classroom?
Both — tune alone, or project “what if…?” demos in class.
Readouts don’t match the formula?
Check units and ranges, then substitute step-by-step from the formula panel.
