## Dynamics 2021

A couple of songs to start this unit. I think we should start all topics with a song.

## Most up-to-date notes,

#### covering all outcomes

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

## Dynamics Summary Notes

Now these appear to be called “Knowledge Organisers!” Who thinks up these fancy names?

This one is a joint effort by Miss Horn and Mrs Physics with formatting help from Mr Risbridger.

These are perfect Mind Maps by Ms Milner, thanks these are the best out!

Other mind maps by Melanie Ehsan, with thanks to eSgoil (who provide lots of online materials), the first of a collection of mindmaps.

## OTHER RESOURCES

A mixture of some notes not yet tidied up!

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

### Waves Summary Notes

These are waves summary notes I’ve produced. Hope you like them. I’d appreciate someone telling me if a photodiode can detect gamma radiation!

## Revision Mind Map

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.

This is a pdf of the power point that I a using

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.

This is the main Radiation post. Start here!

Here’s the video

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

Thanks to Miss Horn who started these off

Radiation Mind Map- only print page 1 and 2. If anyone knows how to delete p3 I’d be grateful for a helping hand.

###### Fusion

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:

1. MONITOR
2. SHIELD
3. 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

## When it goes wrong

17. What was the trigger that caused the man to hang himself?
18. What is the “elephant’s foot?” in the reactor?
19. Have there been any other nuclear disasters? Can you find out about them and name them?
20. What other things did you learn about nuclear power stations and radioactivity?

## Learning Outcome Questions.

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

### Individual Sections

#### Waves

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

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.

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.

## Dynamics

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

## Properties of Matter

20/12/19 finished, thanks to Callum, some corrections made 25/0222

Finished 27/07/20

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!

## Properties of Matter Notes

Not the best fit for a Properties of Matters song, but still lots of important material here.

The Properties of Matter Booklet in both word and pdf form.

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.

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

## ELECTRICITY from 2017

Here is the topic song

Updated November 2019

Electricity 2017 Final word version of the Electricity Unit.

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.

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

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.

#### Components

resistor network Try this when you think you have got to grips with resistances in series and parallel.

#### 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.

Traces

#### 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!
