## Description

Yes, physics is an incredible subject which can explain just about anything, from where the Universe came from to why you aren’t falling through your chair as you read this, but it can also be challenging. It does involve a *lot* of maths, after all. Help is at hand though! As long as you can do all of the maths in this video and in the exam-style question sheet, then nothing that comes up later should seem too difficult.

Just in case you haven’t done enough maths by the time you’ve finished this topic, feel free to head on over to the **Blog** section of the site where you can read articles on **Equations in physics**, **Units in physics**, and **Mathematical relationships in physics**.
