Fluid Surface (Accel / Spin)
This interactive simulator explores Fluid Surface (Accel / Spin) in Classical Mechanics. Linear tank: tan α = a/g; rotating bucket: paraboloid sketch vs rpm. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Suited to beginners and first exposure to the topic. Typical context: Classical Mechanics.

How it works
**Linear acceleration:** in the **non-inertial** frame of a tank accelerating horizontally, the **effective gravity** vector tilts; the **free surface** is **perpendicular** to **g_eff = g − a** (flat surface in equilibrium), giving **tan α = a/g** for tilt from horizontal. **Rotating bucket:** in the **rotating frame**, **centrifugal** and **gravity** combine to a **paraboloid** **z ∝ r²** (here **ω** is a **display** scale, not a lab calibration).
