Sorry, folks. I forgot to post the solutions to the last homework exercise. See attached file which also includes the questions.
dynamics and space
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.

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.
marking information for Nat5 D&S exam questions
Here are the mark allocations for those Dynamics and Space exam questions.
National 5 sample Dynamics & 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.
national 5 dynamics & space summary notes
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.
