Complete Physics Notes for Units 1 & 2

Finally,
These are my higher physics notes for the first two units of the course. The prelim is on Tuesday and I have been trying to finish these for about a week now. Took me a while but got there in the end and so I have decided to do a long awaited blip to celebrate!
