# Quantity, Symbol, Unit, Unit Symbol

I’ve put together, with Mrs Mac’s help, a document with quantity, symbol, unit and unit symbol so that you know the meaning of the terms in the Relationships Sheet. It is in EXCEL so that you can sort it by course, quantity or symbol. Quantity, Symbol, Units the excel sheet

Quantity, Symbol, Units a pdf sheet sorted by course and then alphabetical by quantity.

This is the same information in readily available Tablepress form. If you click on the Higher tab at the top it should sort by terms that you need in alphabetical order, or search for a term. Let me know if I’ve missed any.

## Revision Plan

28/02/18. If you’re stuck inside- DON’T go on your X-boxes, PS4 or whatever the latest number try doing some timed papers.

To the student’s sister who needs the Quantity, Units, Symbols etc .I’ve uploaded the old pre-CfE version and you can just add the additional few. Check out Int1-AH many are relevant. Missing would be t’, l’ etc.

If there is a snow day tomorrow, use the time to look at the EMF material and the test will be as soon as we get back.

__________________________________

This is a ten week revision plan, put together by Mr A Riddell from “up North”. It will give you some ideas on how to break up the daunting task of revision. You don’t have to complete this in the same order, but it does give an indication of how much you need to cover in one week.  ## Tips!

Here I will post a few tips and hints to remember when answering SQA Higher Papers, hopefully they’ll be quick, snappy and memorable. You’ve got the whole of the Scottish Physics Teachers’ Community Wisdom Below!

1. How to remember Cosmic Microwave Background Radiation (spell the whole lot not CMBR, as this isn’t a name) However, the way to remember CuMBRia.
2. Conservation of Momentum IN THE ABSENCE OF EXTERNAL FORCES, MOMENTUM BEFORE THE COLLISION IS EQUAL TO THE MOMENTUM AFTER THE COLLISION.
3. Obviously you know- no secs in Physics, just stick to unit symbols and save all the problems of spelling.
4. Fundamental Particles: Key point: it is not that they can be used to make bigger ‘things’, but rather that they are not made from smaller things.
5. Strong force (associated with the gluon) acts over a very short distance.
6. The gravitational force extends over very large/infinite distances.
7. Neutrons don’t carry/have (net) charge so cannot be accelerated/guided/ deflected by magnetic fields.
8. Remember: SIG FIG, your final answer should be rounded up to the same number of significant figures as the LEAST significant measurement.
9. Don’t forget to revise your uncertainties.
10. Make sure you see the words “end of question paper”. Don’t assume you’ve got to the end and there are no questions on the very last page!
11. “Show” questions – means show correct formula, working and numerical answer stated as given in the question.
12. Don’t leave anything blank! If you really don’t know, give it a go – you never know.
13. The questions in the exam sections (MC and then extended answers) are in approximately the same order as the equation sheet.
14. LIST: given numbers with the correct symbols before doing a calculation. Or as we say IESSUU (information, Equation, Substitution, Solution, Units and Underline)
15. Substitute then rearrange.
16. Read all of the question, especially that bit you skipped over at the start.
17. Don’t forget units! It’s now worth at least 33% of a calculation!
18. This will do for now more to come as they arise……Check out the past paper marking instructions for do’s and  don’ts- its full of them in that second column!

Here are some top tips for Revision from Mr Dawson from Wallace Hall Academy- thanks
