With a little help from the IoP here is my updated Newton’s 3 Laws. I hope you can understand it. I’m quite scared to share it with you! The pdf will miss some detail as I’ve overlapped some images.
This is part of a series of brilliant Mind Maps made by Miss Milner for the N5 Physics Course. I’ve broken it up into sections so here are the waves mind maps!
Here are a list of current wave resources. I will add more as I go through them. Thanks to other schools if you have kindly supplied material. I really appreciate it as do my students.
Reflection is not in the N5 Course, but it is good to know about reflection!
waves-summary-notes-gairloch1 Some of these notes are for National 4, use with the content statements so you don’t spend too long learning the National 4 work.
vflambda-vdt This starts with a practical model that you can complete in class using the Virtual Physics/ Flash Learning. It then shows how v=fλ is equivalent to v=d/t. Finally some questions will let you practise what you know.
Fusion is the process when
two SMALL NUCLEI join to form a LARGER NUCLEI with the production of ENERGY
Fission
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
SHIELD
DISTANCE
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.
To give you an idea of the radiation dose that would occur with radiotherapy, here is my mum’s dose. I know that she’d have been happy to share this with you as a learning experience. I really miss you mum x
At last I’ve completed the LOQ. There are a few mistakes in the answers but really not many.
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.
Enjoy!
Complete book of outcome questions
Final version of the Learning Outcome Questions that are matched to the compendium
This contains the N5 Physics Self Assessment Answers for each unit. Revise with these or use as homework
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 give you more help as to how to get to the answer.
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!
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. NB Please add to this “The length of the line for vaporisation should be longer than that for melting as more energy is required to change a liqued to a gas than a solid to a liquid.
A scribble from an online lesson. The last 2 comments are perfect answers for those “Explain using the kinetic model of gases….” questions.Using a simple syringe will remind you of Boyle’s Law, if you reduce the volume pressure increases. I know this as it really hurts my finger when I squeeze the gas into a smaller space or volume.just some scribbles from an online lesson. We were trying to remember which law went with which rule and this is what we came up with BOYLE’s LAW. If you had a big BOIL and you add pressure by squeezing it the volume increases as it splatters all over the place! CHARLES’ LAW, we know this guy called Charlie and when he gets red hot his face swells up (volume increases with temperature) And GAY-LUSSAC law has been incorrectly attributed to him so we can put him in a pressure cooker (picture below) and increase the temperature. The volume is fixed so we know the pressure increases as the cooker makes a big hissing sound when it’s about to blow!
Courtesy of Wikipedia
Gay-Lussac is incorrectly recognized for the Pressure Law which established that the pressure of an enclosed gas is directly proportional to its temperature and which he was the first to formulate (c. 1809). He is also sometimes credited with being the first to publish convincing evidence that shows the relationship between the pressure and temperature of a fixed mass of gas kept at a constant volume.
Maybe for the deception he should be sent to Pressure Cooker!
A Pressure Cooker
These laws are also known variously as the Pressure Law or Amontons’s law and Dalton’s law respectively.
Thanks to the person on GUZLED who shared these. I’ve redone them so they don’t lose their formatting.https://mrsphysics.co.uk/n5/wp-content/uploads/2021/09/N5-Electrical-atoms.pptx
I can now upload ppp to mrsphysics, so here is one of the first. It is to cover section 9 and 10 of the outcomes. Thanks to the kind person who produced the stuff on A.C and D.C. I’ve been using it for years. Let me know if I’ve nicked it from you and I’ll add my grateful thanks.

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