national 5 assignment – part 2

The second programme is all about the current state of car safety.

We follow a car safety team at Volvo as they prepare to crash two cars together to collect forces data, learn how emergency medicine procedures are changing to improve outcomes for car accident casualties, and learn how sensors are used to monitor the human body’s response to a collision.

Please watch both programmes before Thursday 18th February.

As with the first video, please check you are connected to wifi before downloading as the video file is quite big.

national 5 assignment – part 1

We’re going to start work on the assignment task next week.  You’ll spend 2-3 periods researching car safety online and choosing a particular topic to explore in more depth.  Before we go into the ICT room, I’d like you to watch two videos about car safety.

The first programme looks back at the history of car accidents and the work that has been done to reduce deaths on the road.  While many of the clips shown are quite old, they show just how far we have come in our understanding of the science behind making cars more safe.

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.


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;

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.

Advanced Higher podcast

Higher podcast – includes some past papers

National 5 podcast – includes specimen question paper and the 2014 exam, plus marking instructions

Standard Grade podcast

Intermediate 2 podcast

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.
