ABOUT THIS WEBINAR

Fields are a notoriously difficult field (!) in A-level Physics. The concept of a field dates back to Newton in the 17th Century and then was expanded to include electricity and magnetism in the 19th Century and eventually quantum physics in the twentieth. Students are challenged by the abstraction of the concept of a field – it is invisible but it is fills up the whole of space – and also challenged by the mathematical representation.

In this webinar you gain ideas from Tony on how to tackle the challenges of this topic successfully through analysis of the key conceptual difficulties and review of recent examination questions for the topic.

BENEFITS OF ATTENDING
