I show you how to apply some of the physics knowledge you learn in lessons to answer EXAM STYLE QUESTIONS similar to those you'll encounter in your GCSE Physics exams.

Good luck. Work hard. Be nice.

If questions come up on your physics exams/tests on the topic covered in this video, this video will help you to level up. Do you know each time you get an extra 6 marks (roughly) you go up an extra level. So, it only takes an extra 3 marks to go up half a level! If you understand the content in this video it will easily help you gain an extra 3 marks. #onourway #success

GCSE physics explained is an easy to understand way to help you pass your physics exams, or just satisfy your curiosity about science.

[GCSEPhysicsExplained]

21:11 I should have rearranged the equation to Area = Force / Pressure = 41, 000N / 66, 000Pa = 0.62m2 (the answer and working in the video is right, I just didn't show the rearranged equation, my apologies if this caused any confusion.
