More physics sims
- Levers, spanners and gears simPull on a spanner with a newton-meter at different distances and angles and see the perpendicular distance, read the force that turns the nut and work out its moment; drag the pivot of a crowbar or the load in a wheelbarrow; turn a gear pair and watch speed traded for turning effect.
- Mass and weight on other worlds simHang a load on a newton-meter and weigh it on a beam balance on Earth, the Moon, Mars, Jupiter and in deep space. The newton-meter reading changes; the beam balance does not. Plot W against m and read g from the gradient.
- Mercury barometer simRead a mercury barometer with a metre rule, tilt the tube, widen it and push it deeper to see the vertical height stay at about 760 mm, change the weather and the altitude, work out p = ρgh, and spot the air bubble that makes h too small.
- Metre rule and tape: zero error, end error and parallax simSlide an object along a worn rule or a tape, put your eye straight above each end, read to 0.1 cm and subtract the start from the end.
- Newton's third law with force sensors simTwo trolleys with force sensors tug, push, collide and spring apart. Zero the sensors, then watch both traces come out equal and opposite at every instant, whatever the masses; then sort pairs from balanced forces.
- Pressure in a liquid: depth and density simLower a pressure probe into water, salt water or cooking oil, correct the meter's zero, turn the probe and change the vessel, then plot p against h and work out ρ from the gradient; a can with holes shows the deepest jet spurting hardest.
