Archimedes' Principle – Floating, Sinking and Liquid Pressure

Integrated ScienceForces & MotionAges 13–14

Drag a block and drop it into a tank of liquid: it sinks, floats in equilibrium, or rises to the surface depending on its density compared with the liquid. The weight arrow P and the upthrust arrow F_A = d·V_submerged change length with the submerged volume; drag the pressure probe up and down in the liquid to see p = d·h increase with depth. The readouts and the floating/sinking conclusion update continuously.
