There is absolutely no point in just copying out the answers. There is an important requirement in checking your answers carefully to ensure you haven’t made a mistake and that you’ve understood the course specifications and the learning outcomes.
Only check over the answer when you’ve completed a section and mark them in green pen.
Advice from the SQA
From the Understanding Standards Meeting I went to Physics teachers were advised to tell their students NOT to add in the rearranging line for their calculations. Just do the formula, substitution and final line. For some of you this will involve too many steps so you might want to cross out any middle lines. I’ve shown mine in these answers to hopefully give you more help as to how to get to the answer.
All Units (the maths bit)
Finally finished, but I’ll need to edit out the duplicates but I’ll do that with the updated booklet so the numbers match. (updated 22nd June 2020) Not sure when they will get done, it might be a 2021 version

Please if you find mistakes in my answers please add a comment below.
I will now need to go through and make a 2021 booklet of questions and answers with the corrections. This is a long slow process! I hope you find them useful, then it will have all been worthwhile…… Now I need to start the Higher ones!
