Here is a short summary of the Work topic from the Dynamics and Space unit.
We’ve been learning about forces over the past two weeks. Here are some summary notes to help you with the key points of this topic.
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.
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.

Check you’re using wifi before downloading – it’s a big file!
Sorry, folks. I forgot to post the solutions to the last homework exercise. See attached file which also includes the questions.
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.
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.
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.
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 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;
