Physics Factsheet: 206. Key Experiments 1: The ball bearing “Ski Jump”
A good physicist needs the instincts of both a theoretician (“Aha! I bet it works like this!”) and an experimentalist (“But does it really worklike that? Can we test it?”). Wit...

Physics Factsheet: 208. Applying Kepler's Laws
Ideas about the solar system have changed greatly, but predictions were based on observations of the patterns rather than on being able to actually calculate how the planets moved. It was not until Ne...

Physics Factsheet: 212. Determining Viscosity
The viscosity of fluids is a property that is awkward to define (and also difficult to measure). We picture viscosity as being linked to the “thickness” of a liquid (or a gas). Treacle is ...
