Just wondering if any list members have had experience with teaching physics (or electronics) through their school's community ed (night classes) program? If so would you mind sending me a 'hello' email? I have some questions for you. cheers Tina Kilpatrick Upper Hutt College _________________________________________________________________ -------------- next part -------------- An HTML attachment was scrubbed...

We used to distinguish between the two by indicating that gravity force is the attractive force of the Earth on an object and is evident during free-fall motion when no reaction force acts. Weight is the force of the object on another surface that it is contact with. This implies that when we are in free fall e.g in Earth's orbit, there is gravity force on the object but it is weightless since there is no reaction force on the object. Do other Physics teachers distinguish between 'weight force' and 'gravity force'?? If not why? if so why?

Looking at US6397 for level 3 mechanics I have element 1 asking for three of : angular displacement, initial angular velocity, final angular velocity, angular acceleration, time. Calculations and units. Element 2 asks for rotatioal kinetic energy, gravitational potential energy, torque, rotational inertia and angular momentum. Calculations and units. My question is: For element 2 do I need the students to satisfy all the conditions or just one of them? By the way, does anyone have loads of US tests that they are willing to share with me? I am writing things myself but feel that I must be reinventing the wheel. I'll show you mine if you'll show me yours. Andy, Kerikeri. PS: Try sinking a pyrex test tube in peanut oil. The kids love it. -------------- next part -------------- An HTML attachment was scrubbed...

Stopped doing US6378 since hardly anyone passed that didn't also pass AS2.4 Mech. I'm very happy to share sets of those three (email below). The problem with all these old US is they urgently need a rewrite. The range statement means you must demonstrate ALL of that range unless it says "two of....". For many Physics US with lots of elements and large range statements it makes them very time consuming to assess, reassess, etc. Talking of sharing: I've suggested to David Housden that we all use the new NZIP website to upload our best resources so we can all then download & use the best bits. I tried to start the process & put on some L2 Mechanics PowerPoints. Hopefully some of the lonely wobbly things we all try to reinvent in isolation will come to approximate a circular wheel!!
