What the sim shows
The launcher fires the ball straight up at 3 m/s. Taking up as positive, its velocity falls by 10 m/s every second: +3 m/s at the start, 0 at the top after 0.3 s, and −3 m/s when it is back at the launcher after 0.6 s. The acceleration is −10 m/s² the whole time, at the top too. With a flash every 0.1 s the images are at 0, 25, 40, 45, 40, 25 and 0 cm: going up each gap is 10 cm shorter than the last, coming down 10 cm longer. The velocity-time graph is one straight line with gradient −10 m/s². Taking g = 10 m/s² as in the lesson, with air resistance ignored. Shown at 0.1× speed.

- Thermal expansion simHeat a brass ball until it sticks in a ring and heat the ring until it drops through, watch a bimetallic strip bend away from a contact and switch a lamp like a thermostat, then warm water and air side by side in a water bath and see the gas expand far more than the liquid.
- Ultrasound: sonar and scanning simSail a model ship over a sea bed in a water tank, send ultrasound pulses and read the echo times on an oscilloscope to map the depth with d = v t ÷ 2; then slide a probe over a gel block to get echoes from every boundary inside (and none without gel), and over a steel bar to find a hidden crack.
- Using ammeters and voltmeters simDrag the meters' plugs onto a real bench circuit: put the ammeter in series and the voltmeter across the lamp, red to +, see what really happens when they are wired wrongly (a blown fuse, a dark lamp), pick the range, read the needle to half a division looking straight on, correct a zero error, compare a digital display, and work out the lamp's resistance from your own readings.
- Hooke's law simLoad 50 g masses onto a spring and watch it stretch the same 12.3 mm every time.
- Converging lens simSlide the lamp along an optical bench; the screen finds the focused image from 1/f = 1/u + 1/v (real-is-positive).
- Vibrating string loop simDrag through 8 modes of a closed loop: whole waves fit round it, and f = n v / C climbs 105 Hz at a time.
