Leslie Cylinder
This clip shows how to easily make a simple version of a Leslie cube to investigate the emission of infra-red radiation by different surfaces. This is a required practical for students to be able to understand and carry out for GCSE Combined Science and Physics.
Measure the power of a person and results
In this video clip the power of a person running up stairs is investigated. The subsequent calculations are explained.
A selection of videos aimed at post 16 physics students.
This collection of video tutorials suitable for pupils aged 14 to 16 explain physics in an easy and engaging way.
Physics quantities and units
This video provides a brief introduction to the seven base units used in physics. Base units are identified with their symbols and S.I units.
The origin and definition of the metre is explained and reference to Wikipedia is made for definitions of the other base units....
Polarisation of waves
This video explains the difference between unpolarised light and plane polarised light in terms of using a slit to eliminate unwanted electric wave orientations. It is a continuation of Electromagnetic waves: why they are transverse....
Quantities and units
This short video explains the importance of being aware of symbols for quantities (both scalar and vector) and units. Physics uses letters from our alphabet (both upper and lowercase letter) and from other alphabets (e.g., λ, lambda and θ, theta).
Reflection of light
This video demonstrates an investigation of reflection at a plane mirror. This is a required practical for students to be able to understand and carry out for GCSE Combined Science and Physics.
Refraction of light
A trio of videos that investigates the refraction of light through a transparent block. This first video allows students to see the experiment and the other two review the results and plot a graph to investigate the relationship between the incident and refracted angles. This is a required practical for students...
Resistance of a wire
Two videos investigating the resistance of a wire. The first video allows students to carry out an experiment on the resistance of a length of wire from home and the second evaluates the results by drawing a graph. This is a required practical students to be able to understand and carry out for GCSE Combined...
