More physics sims
- Pressure = force ÷ area: a brick on sand simTurn a real brick onto each of its three faces in a tray of sand and add 1 kg masses, record the pressure each time, and plot pressure against 1/area to see the same force give more pressure on a smaller area.
- Size ladder: atom to Earth simDrag a zoom slider along a powers-of-ten rail from 10⁻¹⁰ m to 10⁷ m and record the real objects that come into view, from a hydrogen atom to the Earth, with their sizes in prefixes and standard form.
- Leslie cube: emitters and absorbers of infrared simPour hot water into a Leslie cube, read a thermopile 10 cm from each face over three rounds as it cools, then time which waxed pin drops first beside a radiant heater.
- Refraction through a rectangular glass block simSet a ray box or pins, mark the ray, measure i and r with a protractor, and find n from the gradient of sin i against sin r.
- Black-body radiation: temperature and colour simTurn up the supply to a lamp and watch its filament go from giving out only infrared to dull red, orange, yellow and yellowish white while its emission curve's peak moves to shorter wavelengths and its total power climbs; then warm a black or shiny can in a lamp's light until it absorbs as fast as it gives out, and see the same balance set the Earth's temperature.
- Charge flow and current simClose the switch on a real series loop and watch the lamp light at once while every ammeter reads the same; drag a magnifier over any lead to see the electrons drift from − to + against the conventional current, time a run, work out Q = I × t yourself (✗ reasons for mA and ms) and check it against a coulomb counter.
