IB Physics: Forces and Free Body Diagrams

Classifies the different types of forces (field versus contact, tension, friction, normal, applied), and then introduce a very simple algorithm to enable you to get your free body diagrams right the first time. Introduces the buoyant force, Hooke's Law force, forces on inclined planes, and sliding friction forces.

"I would just like to say a massive thank you to you for uploading your videos. I started the IB [and]decided to try HL Physics as it seemed interesting. It turned out to be very far from my forté and I was consistently getting 3s and 4s in tests and mock exams. So a few months before the exam period of this year, I began to panic...Then I discovered your channel. For four weeks prior to paper one, I virtually worshipped your videos, and worked along to them in my 'Big Book of Revision.' Last week, I received my results. Incredibly and almost unbelievably, I obtained a 6 in HL Physics. Not only that, but I was 3 marks off a 7."
