I’ve found a producer of some succinct summary notes which I am updating and I’ll post here. I don’t seem to have a full set, but I’ll hunt them out.

Mrs N Hunter Summary Notes

I am extremely grateful to Nancy Hunter from Shetland for these great summary notes. She has kindly given permission for me to upload them here.

Hope they help. I am not removing the Anderson High School as that is where they were produced! Thanks for sharing.

I’m also very grateful to Mr L Mitchell from Belmont Academy for his Key Definitions. I’ve taken the six documents and made them into one document, hope they help. Thanks for sharing!

TopicWord/Term Definition
DAcceleration The change in velocity per unit time. It is a vector quantity and is given by the gradient of the line on a velocity-time graph.
DAverage Speed The total distance travelled by an object measured over the total time taken. The rate of covering a distance. It is measured in metres per second.
DBearing A three-digit number without a degree symbol that can be used to describe direction. It is measured from North (000) in a clockwise direction.
DDeceleration A negative acceleration which indicates that an object is slowing down. The SQA have said they will use the term negative acceleration instead of using deceleration.
DDisplacement The shortest distance between the starting point and finishing point of a journey, which takes into account the direction of travel of the object. The two points are connected with a straight line. It is a vector quantity and is given by the area under a velocity-time graph.
DDistance How far an object has travelled from the starting point to the finishing point of a journey, regardless of its direction. It is a scalar quantity.
DInstantaneous Speed The speed of an object at a particular moment in time. It is measured in metres per second. The time for the instantaneous speed must be very small

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.

Enjoy!

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)

Dynamics

Here is a Christmas Present for all you National 5 students with prelims after the Christmas break. I hope you get more rest than I’m having.

Boy this is slower than I thought or hoped. I hope I get to the end before you do. I’ll keep at it over the next few weeks, at least then it is done and I just need to go through and do the corrections. (updated 21st January 2020)

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.

Waves Learning Outcome Questions

Until I complete the full Learning Outcome Question Booklet, which will probably take me until Christmas 2019 here is the WAVES section completed.

Hopefully by completing all of these questions you will have produced an excellent set of revision notes from which to revise.

You can always use these in electronic version to answer the questions but DON’T think you’ll produce one set between you and copy!

Dynamics 2018

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.

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.
