The flywheel and the residuals - when R-squared is excellent and the answer is wrong

A flywheel turns on its axle, a weight hangs from a string and falls one metre. A stopwatch…

Density by Archimedes — when subtracting two numbers ruins everything

You weigh a sample in air, then weigh the same sample in water. The difference between the two…

Lab: Coefficient of Friction

Measure a coefficient of friction without ever weighing anything. Raise the board slowly until the block slips and…

Lab: Hookes Spring

Hooke's law experiment: measure spring constant k from the F-x graph, ruler uncertainty, and linear regression with Python…

Start Experiment

The spring constant two ways — when both methods agree and both are wrong

You have one spring and a set of masses. One way is to hang them and read the…

Start Experiment

Young's modulus — the experiment you must break to know where it was valid

You hang weights on a steel wire, one kilogram at a time, and read its stretch to a…

Oscillation & Waves (2)

The pendulum and the averaging trap - the error bar shrinks, the answer stays wrong

One pendulum, one stopwatch, and patience. Every time you time twenty swings your error bar gets a little…

Start Experiment

The speed of sound - when discarding bad data pushes the answer toward what you expected

Three stamped tuning forks, a resonance tube, and a number printed everywhere: the speed of sound is 343…
