deriving the equations of motion December 30, 2008
Posted by mrmackenzie in : Higher, podcast , add a commentI’ve been looking through the results of the traffic light survey we did at the end of unit 1 of the higher course. The learning outcome that most people were unhappy about was the derivation of the equations of motion.
I put together a handout that outlines where the 3 equations come from, starting with a simple velocity-time graph. Let me know if you think your understanding of this outcome would benefit from the video treatment I have used in your homework solutions.
Standard Grade half-life calculations December 28, 2008
Posted by mrmackenzie in : Health Physics, Standard Grade , add a commentFor those of you preparing for S Grade prelims straight after the Christmas holidays, I have added a 6 page summary on radioactivity & half-life calculations with worked examples and extra questions (with answers) for you to try.
You’ll find the pdf file containing all this radioactive goodness in the Health Physics section of the Standard Grade revision page.
Youtube solutions to latest Higher HW December 16, 2008
Posted by mrmackenzie in : Higher, homework solutions, screencast , add a commentHere are the youtube clips showing the solutions to the HW due on 15/12/08. I’m going to ask for your help in assessing an alternative video hosting site called Vimeo.com.
After the Youtube videos, you will see the same solutions again but this time they will be presented via the Vimeo site. Please leave some comments so I know which of the 2 presentation solutions your prefer. Thanks.

Higher HW solutions Q3 (due 15/12/08) December 15, 2008
Posted by mrmackenzie in : Higher, homework solutions, podcast , add a commentThe solution to Q3(a) is contained in the attached video file. Solutions to the other parts of Q3 are: Q3(b) The gas is at constant temperature. Q3(c) The volume of the oxygen tank will always have some gas in it, so not all of the 75 litres of air are available for the astronaut to breathe.
