PAPER 2MULTIPLE CHOICE QUESTIONS

AQA (9-1) GCSE PHYSICS PRACTICEThis booklet contains multiple choice questions designed to help you prepare for Paper 2 of your Physics exam, on Friday 15th June 2018.

The topics that are covered in Paper 2:Topic 5 – ForcesTopic 6 – WavesTopic 7 – Magnetism and ElectromagnetismTopic 8 - Space

All questions in this booklet are designed to test the content of the AQA GCSE Physics examination but are not in the same format as the questions that will be on the paper. The intention of this booklet is to aid in the assessment and revision of the material on the specification, not to familiarise the students with the question format.Questions that are exclusively higher content only are marked as such, but otherwise all questions are linked to content you may be tested on in either paper.

Each question in this publication has one answer only – A, B, C or D.A full set of answers is provided at the end of the booklet.

Print the following pages 2 to 1, to save paper!

If you are struggling with the questions…

There is a range of resources you can use to recover the topics:1. Your classwork will contain a lot of practice and explanations for

each topic2. EzyScience – the website contains a vast amount of videos for you

to learn from3. Youtube – We have taken short bitesized videos from youtube and

made them available on Moodle for you to watch to further revise each topic.
