about exco treat and things

well...

sorry for waiting zp. i know you have been visiting my blog and find no updates, or you have give up already? never mind.

really have a fun time at the exco treat, all thanks to anna and CL. i know it cost a bomb. we really enjoyed it! I eat until i cannot bend down! whats more interesting? i manage to pian 4 people!! haha.. sorry pals, for having betrayed your trust on me, that i am a honest person who never play trick on people. really cant help myself. sorry anna and yantong. i trick you two time. hehe

it is really my first time going into an arcade so enthusiatically with the urge to try out anything that i would have thought...."illegal" to me. come to think of it, i have did alot of things that i would not have dreamed trying. first arcade, then mah jong. but well, i think i feel the omen that i should not go arcade often since i forget to take my bag and went all the way back.

talking about going back to take my things, i really have to thank my best friend zp. today i really feel that i have you as the best friend. you are running like its your bag that is left there. really....thanks.... then in the shuttle bus, i saw you talk to the 2 little friends there. although you dont know them, i think your friendliness had told them that you are nice ppl. haha... gotta learn from you beh....

ok... after the arcade, we went to Geraldines house to play mah jong. nice mah jong set and table you have Gery! well... it looks nice. i think i learn quite fast. at least i now know how to play basic mah jong and dont have to be embarrase about not knowing how to play. really thanks seok hui and anna for their patience....really found it weird to teach mah jong in eng but well... nvm

oh ya... in the mrt... i think some of the sharks got see me writing things in my note book. i was thinking about work done and force and E=mc^2 and Nm and K.E. and those things. got some enlightenment. haha.
i managed to derive that work done is equall to mv^2 from the definition that work done is the product of force and distance. i subt in F=ma. since a=v/t and v = d/t, therefore, F= m(d/t)^2 . since d/t = v, therefore W.d. = mv^2. then i look at formula of K.E.= 1/2 mv^2. i have thought that K.E. is energy and workdone is energy also and they are the same. but from this i can see that they are not equal. so why? and is K.E a subset of W.D.? what is the other 1/2 mv^2? is it potential energy? or is it nuclear energy? then... since w.d. is force x distance... then what is the force here? should we imagine force like a hand pushing or pulling or like the engine of the rocket? what are we actually calculating when we calculate force x distance? logically speaking... it dont quite mean anything, and there is alot of grey areas. like when you puch something and it does not move. energy is still lost... as thermal energy... so why are we not considering those energy and just think they are not....affective work done.... ok its not....but... can we calculate the total energy used? including thermal energy? some more. wait.... what is the use of calculating W.D. ? we dont really use it to calculate...K.E. or GPE. ... may be for calculating calory... nvm.... i just find alot of grey areas in the fields of knowledge on work done and energy and things... abit abstract....

well... enough physics... may be i can start posting all my funny physics questions here...may be someone can enlighten me?

ok... enough for today
