A couple of weeks ago I wrote about a neat way that two of my students had devised to draw straight lines in the falstad ripple tank applet well I have found a better way. I've been using this superb applet for about 10 years and have always struggled with straight lines. The situation I want to recreate is a plane wavefront incident on a straight reflector. The line goes straight for a while...
This is a great resource for IB Physics teachers. I have been using it and will continue using the same in future. The resources of IA are great. I can strongly recommend to any Physics teacher of the world for this site. Thank you for maintaining the...
This site is well organized and thorough. It gives great insight into the content and how connections can be made for students. I have been using it to help me prepare for the 2016 assessment, and have used resources for each content area and laboratories...
InThinking Physics is a valuable resource. If you are teaching IB Physics for the first time, then it is an absolute must-have. The materials provided are practical, easy to follow and full of interesting resources.

Simulating an object oscillating with SHM in GeoGebra is easy but simulating a pendulum is tricky. The problem is that a pendulum bob moves... more

Electric fields simulation (GeoGebra)Hi; Select the vector tool from the "line" menu. Then draw a vector from the point representing the charge to the point representing the test charge (probably A and B). This is exactly the same as adding a line segment except that it has direction....

Electric fields simulation (GeoGebra)Hello We are not quite clear on how to do this step : Add a vector joining the points from Q1 to the test charge. (vector u) Thanks

Charging and dischargingYep, you're right. Have made correction, thanks.

Charging and dischargingI like your questions solving for C and R from the charging and discharging graphs, but both graphs look like RC is clearly 1s not 2s.

No one expects the Spanish inquisitionRight, I understood it only when falling asleep. But it's good I could ask and got an answer :-)

No one expects the Spanish inquisitionIt's certainly a very tricky one. Newt 1 gives F - kv = ma so F = ma + kv Power = Fv = mav + kv^2 v = at so P = ma^2t + ka^2t^2 Quadratic so D To be nit picky, line d isn't actually a parabola, I tried doing a parabolic fit in loggerpro and...

No one expects the Spanish inquisitionI agree, I have just one question about the answers on OCC: TZ2 SL P1 question 8 (the one with graphs of power developed by train engine versus time) the answers say C or D, but I would say B - there is constant acceleration hence P = v F...

No one expects the Spanish inquisitionNice summary. IN my teaching I've used the old syllabus as a guide to what students need to learn to State and Define. We'll see if it helped!
