If you need help with Physics, you're in the right place. The Physics
Boot Camp team has decades of experience of helping students of all
abilities improve their GCSE Science Grade.

This course includes video lectures for every section, downloadable worksheets (with answers) for practice and a summary quiz for each section. Before you spend money on a private tutor, try our course - you can access the course when and where it suits you and the whole unit costs less than one session with a tutor!

This course covers the unit P4 - Radiation for Life, which is part of the OCR Gateway Additional Science or Physics B course. If this is not your exam board or course, then check out our instructor page for a suitable course for you.

In this unit you will learn about why some materials are radioactive, the
properties of the three different types of radiation, their uses and
effects. You will also learn how circuits work, how static electricity occurs
and the use of electricity in the home.

We use our expertise from helping thousands of students to highlight the key areas that you need for your exam, along with helping you avoid the mistakes that everyone else makes!

Background music: Nicolai Heidlas - Sunny Afternoon, Hawaiin Winter, Summertime

Electric Charge
7 Lectures 36:14

Understanding the movement of electrons is essential for getting to grips with electricity and that's what you'll learn about here. Static electricity also includes the best ever physics demonstration so make sure you check out the van der graaf generator videos in the resource section

Preview 07:50

Static electricity isn't just for keeping physics students (and teachers) entertained in the laboratory - it has a lot of real world applications and we'll learn about three of those here.

Using Electrostatics

Circuits don't work by magic but often students think of them in that mysterious way! This session will help you understand what is actually  happening in the wires in a circuit.


Why does electricity move around the circuit in the first place? Thissession will help you answer that and apply your knowledge to analyse circuits.

Potential Difference

The relationship between voltage, current and resistance is essential to understand what is happening in circuits. We've done current and  voltage in the last two sessions... so guess what this one is about!


Describe what is happening in circuits in terms of energy transfers
Energy Transfers

You put a plug in a socket and, as if by magic, electrical devices work in your home. This session will help you learn about how the 'magic' happens!

Radioactive decay equations cause problems whenever they appear on exam papers and you'll learn how to master them in this session.

Preview 08:22

It's important to be able to describe the differences between the three types of nuclear radiation and that's what you'll learn in this session.

Types of Radiation

We are exposed to radiation all the time and this session will look at where that comes from.

Background Radiation

Half-life questions are an examiner favourite and there's nothing to them... honest!
