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 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
When neutrons split nuclei by fission and extra neutrons are produced which can split further nuclei. Large quantities of energy are produced.
exposure to ionising radiation.
There are 3 groups of category to reduce harm caused by
includes things like wearing radiation badges or EPUs, timing how long you are
exposed to radiation, checking with radiation counters any contamination on
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.
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.
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!
These laws are also known variously as the Pressure Law or Amontons’s law and Dalton’s law respectively.
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.
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.
