Higher HW for Friday 16 January
Your HW sheet with questions on EMF and the Wheatstone Bridge is attached. Please hand it in no later than the above date.
deriving the equations of motion
I’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
For 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.
equations of motion – projectile motion
How to separate out the horizontal and vertical motion of a projectile and apply the equations of motion.
equations of motion – combining up & down vertical motion
This is an example showing the importance of adopting a sign convention at the start of your problem.
equations of motion – final velocity
An example illustrating how to determine the final velocity of an object when initial velocity, acceleration and distance are known.
