IloveIB! Posted September 13, 2011 Report Share Posted September 13, 2011 What can i do/find with a ping pong ball? Any ideas? I was thinking of finding the time it takes for the ball to stop bouncing as you change the height!! LOL Reply Link to post Share on other sites More sharing options...
Guest KAPOWW!! Posted September 13, 2011 Report Share Posted September 13, 2011 What can i do/find with a ping pong ball? Any ideas? I was thinking of finding the time it takes for the ball to stop bouncing as you change the height!! LOL Aaah!! Doing IB in Mauritius must make it a lot less worse, with those beaches!! *Sigh* Hey that's not such a bad idea for a start btw! Here's a very cool idea: you can use a video analysis software to record the varying amplitude with time. If you like this, Wall post me or PM and I'll help you further. Note: the IBO requires some IAs that use instruments and graph plotting software etc. So this kills 2 birds with one stone All the best cheers!

dessskris Posted September 13, 2011 Report Share Posted September 13, 2011 that's too sophisticated. your experiment doesn't have to be so awesome or so technological.it's better to find the number of bounces in a certain time period. it's a lot easier and a friend of mine did it as his design. if you count till it stops bouncing, wahlao when the height is 1 m it'll take quite a long time eh!

Erm no it makes no diff, let me tell you!! you've actually got a good idea I will think about it... But say if i was doing it like i suggested, what would be the controlled variable?
