For those of you who have found the dynamics and space unit quite long and hard to remember, you might want to start with these revision notes instead. Don’t forget that a fuller set of notes is available here.

nat5 latent heat of fusion/vaporisation
Those experiments to determine the latent heat of fusion and latent heat of vaporisation for water bring the dynamics and space unit to a close. Here is a copy of the handout we used in class. You will be tested on this unit in your double period next week, so please remember to download a copy of the summery notes to help with revision this weekend.
what do astronauts do?
We’ve been looking at the risks and benefits of space exploration.
Tim Peake, the British astronaut about to start work on the International Space Station, appeared on The One Show last week to talk about his training for the mission.

higher outcome 1
We’re going over your drafts of the Outcome 1 report tomorrow.
For those who have mistakes in the raw data, a pdf version is attached below.
Nat5 dynamics & space revision notes
Here is a set of revision notes to help you prepare for the upcoming dynamics & space unit assessment. Ignore any references to specific heat capacity on pages 49 & 50 – we’ll cover that in another unit and it won’t be in your D&S test.
Thanks to Mr Noble for sharing his notes 🙂
satellites
Satellites are similar to the horizontally launched projectiles we looked at last week. A satellite moves horizontally at constant speed but also accelerates vertically towards the planet’s surface due to gravity. Thankfully, the curvature of the Earth means the satellite doesn’t crash but keeps on orbiting the planet.
According to SQA, National 5 candidates need to know about the
Impact of space exploration on our understanding of planet Earth, including use of satellites.
So far this week, we have covered many applications in which satellites are used to study our planet. Examples include;
monitoring volanoes
weather forecasting
climate change
Nat5 – solutions to scalar/vector hw exercise
Here are your solutions to the homework questions on scalar and vector quantities. Check your own work against these answers and let me know if you need any further explanation to reach the answers shown.
higher homework solutions – forces
Here are my worked answers to HW4 on forces. Please speak to me if you still have questions and working through the attached file.
Note that other methods are possible for Q5a(ii), e.g. sine & cosine rules, or a scale drawing.
this site is moving…
Many of you have encountered error messages while using this site. It’s outgrown the current hosting service and I’m moving to a new provider. Please bear with me while I transfer everything across to the shiny new server.
If you discover any links that have stopped working, please leave a comment in the affected post/page and I’ll fix them as they are reported. Thanks.
what to do if the website is busy
You might have noticed that the server has struggled to cope with so many people trying to view the resources as the Physics exams approach.
If you can’t get in, you can still access some of the video files and PDF notes through iTunes.
There are iTunes podcasts set up for Advanced Higher, Higher and National 5 Physics. Those of you sitting National 5 might also find useful resources in the old Standard Grade and Intermediate 2 podcasts.
Higher podcast – includes some past papers
National 5 podcast – includes specimen question paper and the 2014 exam, plus marking instructions
Subscribe to the appropriate podcast and download the pdf/mp3/mp4 files. I’ve run some tests and this seems to work even when though the site won’t let you in.
