Free physics notes and video lessons

Home schooling and the Covid19 (coronavirus) epidemic.

As many students around the world are suffering home schooling these are all free resources that may help to support you. Many sites, for example BBC bitesize are more comprehensive but these notes contain many videos showing practical demonstrations together with the explanation.

These Notes and explanations are on easily downloaded PDF sheets and they cover most of the more difficult physics topics (and some of the easier ones!) aimed at students and their teachers in the 15 to 19 year range, as well as enquiring adults.

**Recently added video lessons and pages include:

Momentum conservation a worked example calculation using easy numbers to demonstrate a method useful in examinations

Momentum and momentum conservation - a demonstration of the Law of Momentum using simple equipment to perform an experiment easily replicated with basic everyday resources.

Ions and Ionic bonding  explaining how exchange of electrons leads to stability

Ionising radiation and the Geiger counter  explaining how ionising radiation triggers a reading in a Geiger Muller tube

Sparks - ionisation in an electric field  - an animated explanation explaining how a single ionisation causes an avalanche of electrons and a spark, arc or flash of lightening.

What a capacitor does and how it works Explaining quickly with practical demonstration and animation how a capacitor stores a small amount of electrical energy.

Farads - measuring capacitance the video lesson explains the definition of this unit of capacitance and that capacitors used in electronic circuits are tiny fractions of a farad

Steradian - an explanation of how we measure a solid angles.

What is a radian In more advanced physics and maths angles are often measured in radians rather than degrees. This short video lesson explains the connection

Isotopes explained using graphics and examples

Links and support

If you are a student preparing for examinations it is essential that you revise well and that you practice examination questions. You must check your answers with your teacher if you can or with standard answers provided by the exam boards.

To help you revise I have listed some links to other websites I think might help. These include those with useful notes although not usually much video. I have only chosen those which seem to me to be authoritative and accurate. There are also links to the A level physics syllabus of all UK exam boards who almost all provide past papers and mark schemes.
