Simulation of Friction, lubrication – Piston in an engine cylinder

Simulation of piston sliding back and forth inside an engine cylinder This simulation shows a piston sliding back and forth inside an engine cylinder, demonstrating how lubrication reduces friction. A blue arrow on the left shows the driving force pushing the piston; red arrows on the piston show friction resisting its motion each stroke. Three […]

Simulation of Friction, lubrication using a crate

Simulation of Friction, lubrication using a crate This interactive GCSE Physics simulation shows how lubrication reduces friction between surfaces. As you increase lubrication, the friction force drops, so less energy is transferred to the thermal store (less heating/heat trail) and more of the work done by the push goes into the object’s kinetic energy (it

Giant Ionic Lattice and ionic bonding Simulation

Giant Ionic Lattice Simulation — Description The simulation shows a 5×4×4 NaCl lattice of 80 ions rendered in 3D using Three.js. Na⁺ ions appear purple and smaller, Cl⁻ ions appear green and larger, reflecting their real relative ionic radii. Yellow lines represent the electrostatic attraction between each Na⁺ and its six adjacent Cl⁻ neighbours. Students
