More physics sims
- Three forces in equilibrium: the triangle of forces simHang a load from two newton-meters, read the tensions and the angles, then draw the closed triangle of forces to scale and check it against the meters.
- U-tube manometer simJoin a U-tube manometer to the gas tap, a flask squeezed by a syringe or your own breath, read both levels to the nearest mm, find h and work out Δp = ρgh and the gas's pressure, then swap the water for oil or mercury and widen one arm to see what changes.
- Walk the graph: match a motion graph by walking simWalk in front of a motion sensor so your displacement–time, velocity–time, distance–time or speed–time line matches a target, then measure it with the gradient and area tools.
- Work done and power simDrag a newton-meter to pull a box along the bench and lift a load up steps, read the force and the distance moved in its direction to find W = F × d, then weigh a runner, count the stairs and time them walking and running to find their power P = W ÷ t.
- Waves on a string simTune a vibration generator until standing waves appear, measure the nodes, and find the wave speed from v = f λ and a graph of f against 1/λ.
- Appliance power and the electricity bill simSwitch on a kettle, toaster, fan and LED lamp, set a timer, run them and watch an energy meter count kilowatt-hours, then record each run and work out the cost at a price per kWh you choose.
