In this Podcast I go over 4 of the 21 equations that you need to learn for GCSE Physics. You must be able to write these down correctly and use them to solve problems. Knowing what the letters mean and how they arranged in the equations will really help your understanding and ability to answer exam questions.

I will go over the equations for work done, power and the two ways of writing the efficiency equation. These equations are used to describe key areas of physics and lay the foundations for the work that we will do later in the electricity, particle model, atomic structure, forces, electromagnetism and, if you are doing the Triple Physics course, space as well. Understanding energy really is that important.

If you are listening to this on the school Blended Learning Platform, please complete the short survey afterwards so that I can produce more content to support our learning.
