Here are the mark allocations for those Dynamics and Space exam questions.
Here are some questions from the old Standard Grade and Intermediate 2 exams that fit the dynamics and space unit of National 5 Physics. I will provide solutions in the next post.
Here are some summary notes for those of you about to resit the Dynamics and Space unit assessment. Don’t forget that there is additional material available on BBC Bitesize.

It turns out there are many challenges to be overcome if we want to send astronauts to another planet, e.g. Mars. Earlier this year, the BBC Horizon programme looked at the issues. Here is the episode. I have split the film into three parts.

We’ve started looking at telescopes and this BBC programme from 2 years ago featured the replacement for Hubble, the James Webb Space Telescope. The presenter, Maggie Aderin Pocock now hosts The Sky at Night on BBC4.
Please take some time to watch both parts of the film. Maggie covers the basic idea of satellites, how we achieve geostationary orbit, looks at examples of Earth observation and the manufacture of the James Webb’s massive 6.5m mirror. In part 1, around 17 minutes in, you’ll see satellite footage over the Highlands, can’t quite see Thurso though.
