This is the main Radiation post. Start here!

Thanks to Miss Horn for the Radiation Notes. Worked Answers to follow.

From Helpmyphysics


Fusion is the process when two SMALL NUCLEI join to form a LARGER NUCLEI with the production of ENERGY


Fission is the process when two large nuclei split to form two smaller nuclei with the production of energy. This can occur spontaneously or due to a collision with a neutron. Often extra neutrons are produced.

Chain Reaction

When neutrons split nuclei by fission and extra neutrons are produced which can split further nuclei. Large quantities of energy are produced.

Reducing exposure to ionising radiation.

There are 3 groups of category to reduce harm caused by radiation:


Monitor includes things like wearing radiation badges or EPUs, timing how long you are exposed to radiation, checking with radiation counters any contamination on clothes.

Shielding is placing layers of absorbers between you and the source, BEWARE, goggles and a lab coat are great at protecting against alpha but have no effect on gamma. Only thick layers of lead would offer protection against gamma.

Distance. Radiation obeys the inverse square law, as you double the distance from a source the level you are exposed to decreases by ¼ . Using tongs is an effective method of keeping your distance from a source.

Learning Outcome Questions.

At last I’ve completed the LOQ. I am sure I’ll find mistakes when I produce the answers. I will get those done a.s.a.p, but they take a lot longer to type up than write up.

When completing these questions there is no point in just going straight to the answers, it wont teach you anything. Use the answers after you’ve completed what you can do and had a good guess at what you can’t. Mark in green anything you’ve had to look up.

Final version of the Learning Outcome Questions that are matched to the compendium

Individual Sections





Properties of Matter



This also contains some bonus material on problem solving questions. You’ll find these in every paper.

Learning Outcome Answers

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)




Properties of Matter

20/12/19 finished


Making Progress, but can’t quite keep up with all the unknowns of the current health situation. If anyone is self isolating and wants to type these up, please do so! Need to finalise answers 4th July 2020 still some way to go but I’m working on it

Space Learning Outcome Questions

Currently these are just a draft set of questions and I’ll change them when they are completed. These will be sufficient for you at the moment.

Dynamics 2018

The latest version February 2020

This is the updated version of the Dynamics booklet, updated to match the 2017 SQA changes.

The materials below I’ve just uploaded from my Intermediate 2 folder and thought some of this might be useful. It’s a quick upload and I’ll sort it out when the rest of the development work is completed (hahaha). Currently I’ve a prelim to write and get copied for two weeks time.

Here are some practice questions with worked answers and 6 to a page diagram of the sky diving graph

Learn these Experiment

Thanks to S Gray, Drummond Community High School,  for putting together this book of experiments that you should have covered in your N5 Physics lessons. Any of these could be discussed in your exam as a question.

Here are a set of summary notes, I made a few changes and put them into a table rather than boxes to help the flow, not that anyone would know. Thanks to the teacher who produced these- sorry there was no name on them.

A bright 2 page set of summary notes for this topic.

Thanks to other Physics teachers who have provided resources for these notes.

Electricity 2017 Final word version of the Electricity Unit.

Electricity 2017 Final  pdf version.

The booklet is large as it contains lots of questions for you to practice, practicals for you to complete and notes.

They are large notes so that you ought to be able to work your way through whether you are in class or away at college etc.

Please return your copy to the faculty on 30th April 2020!

The section numbers are linked to the compendium with all the things to cover in National 5 Physics.

Thanks to the person on GUZLED who shared these. I’ve redone them so they don’t lose their formatting.

Ohm’s Law

Feeling brave- this isn’t as hard as it looks, but you can impress your friends and family.

Other notes

Mains- Electricity in the home

Here are some additional notes that might help as you go through the materials. Check out the post on using your calculators to measure resistance (I’ll add the link here when I’ve found the post!)

Ring main   Based on the SG course notes and not really in the N5 course, but it might give a little background to why when calculating the fuse rating for an appliance you use 240V and not the 230 V as stated.


Older Notes

EE1 – Electricity LOCKERBIE The old electricity notes (based on a colleagues work- thank you and I’ll find out who you are), these will be superceded when the document above is completed.

Elect & elect D&G Prob Book no answers These are some great little questions by Mr Belford from Dumfries Academy, but some of the numbers are a little bit fictional!
