The InThinking Physics site has been a life saver. Chris's explanations of syllabus content and assessment criteria have helped enormously with planning and programming. The inclusion of marked IAs in particular was really beneficial when I started teaching...

    Hi Brad; I finish the whole IA in May of year 1. I find this works well, students are fresh, awake and not bogged down with other deadlines. In preparation I do a mini IA in the first term.

    I was curious though - How does the IA fit into your plan? How much of the IA can realistically be completed by the end of DP1?

    Thanks for describing your sequence Richard. I also have SL/HL combined classes with an additional 30 min HL block that occurs once every 4 classes. So the first few of these blocks may not be used as effectively, but once the students learn...

    Cheers Brad. I've been living with Norwegians so long I'm beginning to spell like them. Now it's corrected I'll have to explain the joke, I spelt his name Jeger which in Norwegian is pronounced Yeger. Just my attempt at excusing my poor spelling.

    Hi Chris, Do you have anything on drift speed? Thanks, Benson
  • Hi Eric; Excel agrees with me that 0.025 should be rounded up to 0.03.
  • Hi Chris, I think if you rounded to 1 sf must be 0.02%, cause 0.025% should be rounded to the closest even number. is it?

    Hi Fergus; Good point. The resultant force on the ball = N-W but the force on the ground is N so I should add W. I'll change the question to the force on the ball.

    Hi Chris. In question 2, have you ignored the weight of the ball because it is so small compared to the upward force of the ground? Thanks, Fergus.
