Physics remedial was so interesting..


1.) Mr Ong brought a fan to the classroom and called us to wave our hands infront of our eyes at a rate of 90o times per minute while looking at the fan which is turnd on and then guess wad?!?! The fan is supposed to appear stationary!! oh my god~~!


2.) In addition, yichun also went up to do a demo with joel as he had some questions on circular motion. He called joel to swing him in circular motion and then to release the hands halfway while he was being swung.. then he was flung to the door.

... He then asked, " Why don't I feel being sucked to the middle since there is the existence of centripetal force?"

3) Mr Ong brought a hairband with two springs on the top (look at pic) to the class to demonstate the concept of oscillation. He asked Jeremy (someone from 06s6h) to wear the hairband and swing his head from side to side at a certain frequency and to observe the two springs...

I took some photos during physics remedial but i cannot upload it.. nvm..

Anyway, jiayou for your block tests and see ya when school reopens!!
