Last week we learned about vectors and I showed you the scale diagram method for solving a vector problem, such as determining the displacement of an object after a journey. The video is a short re-cap of the scale diagram technique.
By now you should have watched the video about satellites. This screenshot showing a satellite passing over the Highlands was taken from about 17 minutes into the programme – did you notice at the time? It was quite eye-opening to see just how much modern society relies on ... Read more applications of satellites
In space there is no air resistance to oppose motion, so the Space Shuttle orbiter could travel at very high speeds, up to 17,000 mph! At these speeds, the orbiter experienced enormous air resistance as it descended into the Earth’s atmosphere at the end of its mission. Air resistance is just like any other form ...

Here are the solutions to the dynamics & space questions. I have adjusted the marking instructions to reflect the way national 5 is marked.
Here are the revision questions for dynamics and space. They are taken from old standard grade and intermedite 2 past papers. I have adjusted the marks to fit national 5.
Here is the second set of revision notes for your test.
Use the attached file to help with revision for your test on Monday. Start at the beginning of the booklet and read up to the end of page 41. Thanks to Mr Noble for sharing his notes. 🙂
//www.youtube.com/watch?v=QK5Bxf3Pov0 We’ve been looking at work and the rate of change of energy. This handout will help you to revise the key points and introduces gravitational potential energy.
Today we examined the importance of Newton’s 3rd law of motion. In our discussions, different explanations for the motion of jets and rockets were proposed and considered. The front runners were; at launch, the ground pushes back against a rocket during flight, air pushes back against a plane Unfortunately, the lack of ground and air (or ... Read more
