Physics Playground
Predict it, then watch it happen
Balance a lever, guess what floats and what sinks, and light up the bulbs. Every answer is worked out with real physics: moments, density and current. Three quick rounds every day.

Modes · 3 modes
Lever
Put the load where the beam balances.
Float or sink?
Tell which objects float in the liquid and which sink.
Light the bulbs
Work out which bulbs in the circuit light up.
What you will learn
- Use the law of the lever: mass × distance is equal on both sides
- Predict floating and sinking from density = mass ÷ volume
- Trace the current through series and parallel circuits
