A short video showing a simple classroom method of checking the way in which this force is related to mass, speed and radius.

A presentation showing both the ideas about centripetal force and a simple classroom method of checking the way in which this force is related to mass, speed and radius.

A short clip showing the experimental measurement of the speed of electrical pulses in a cable - a large fraction of the speed of light.

A presentation showing how to measure the speed of sound over a short distance on a laboratory table.

A short clip showing the measurement of the speed of sound over short distances.

An introduction to constructing and recognising chemical formulas. Using 20 well-known elements, the valency-rules which govern the atomic ratios are explained and used with several examples.

An introduction into the writing down of fully balanced chemical equations. The process is explained starting with word equations, finding all the relevant formulas and then working with some useful rules for finding the correct coefficients in the b....

The concept of oxidation and reduction is explained and generalised using oxidation numbers with ionic and covalent examples. Several equations are balanced, using the oxidation number method to fix various atomic ratios.

The main problems associated with communicating with distant space probes like Voyager 1 are investigated. The role played by diffraction in limiting the amount of power receivable on Earth is discussed. The further problems of reaching a nearby st....

A brief look at the Physics behind sending signals along cables and via geostationary satellites. An experiment to measure the speed of an electrical pulse in a cable is described and the Physics of the orbits of communcations satellites is develope....

A look at what was known when Newton started to develop his theory of gravitation and how he used these ideas and data to make his great forward step

A survey of the variety and usefulness of the wide-ranging techniques which incorporate the name spectroscopy.
