30 may 2010 -Physics Revision ( if u find it difficult to memorize read this )

this is adapted from gio's notes.

dont laugh i know its silly but it works for me.
this is somekinda stupid plot i made up, i find it easier for me to absorb silly stuff.
like how i can easily memorized chonny's line in his vid but not this physic's note after several hours staring my eyes out.


Measurement
let 10^age

giga is twin with nano.
giga's age is 9 and nano's age is -9

mega is twin with micro.
mega's age is 6 and micro's age is -6

kilo is twin with mili.
kilo's age is 3 and mili's age is -3

deci has a sister name centi
deci's age is -1 and centi's age is -2

kevin and celcius are friends. kevin is shorter than celcius. he figured that
he need to add 273 more to be the same height as celcius.

meter rule's youngest child is 0.1 cm and 1 mm

think of vernier, micrometer and error as people. (let ur imagination go wild people!!)
vernier and micrometer is currently avoiding error.
they think that if they check the zero error, they will be free from error.
but they forgot to position their eye directly above the markings that is to avoid parallax error. at the end, they met error. =.=


kinematics

speed marries time and they gave birth to distance.
s x t = d

the boy speed change into a girl speed after he do the 'displacement/unit time' operation. (dont get it? move on!!)

acceleration = (old speed - young speed )/time

force
force is always pull her sister hair and push anyone that block her way.

Fn was looking up when suddenly weight fall on to him. tension tried to pull the door open but friction was holding on to it on the other side of the door.

vector got 4 children.
names are
davin ( displacement )
vina ( velocity )
faustine ( force )
and aldwin (acceleration )

scalar got 7 children. *wuoh subur!*
she call them DISPIENTIVODENPO *sound like french he?*
DI stance
SP eed
EN ergy
TI me
VO lume
DEN sity
PO wer

movement will stop, accelerate then decelerate if u give her force.

newton's second wife is called force.
force is the daughter of mass and acceleration
force  = mass x acceleration

friction can sumtimes be good. he will help in braking and holding onto chopsticks.
but he will also be bad , and will lower the efficiency of the car by 20% causing it to wear and tear of moving parts in engines, motors and machines.

mass weight and density
mass's nickname is KG
wieght's nickname is N

weight is taller than mass since it can reach to the centre of the earth.

earth is n/kg or 10m/s
moon is just 1.6n/kg or 1.6m/s

weight got married to gravitational field and gave birth to mass.
weight x gravitational field = mass

inertia is one lazy fella that always rest. that fella is also apathetic (reluctant lor!)

inertia like mass. so, if mass turns big, inertia will also join mass. if mass turn small, inertia will follow too.

mass rejected inertia becoz that fella is to ignorance . mass marries volume and give birth to density.
mass x volume = density

so guys, mass got 2 wifes.
mass x volume = density , and
mass x acceleration = force.


stop giving me that face !! im just tryin to help here :P
XD hope that cheer your day. even though i think no one will care to read this sort of trash *cry in the corner of the room*

good night guys! im waiting for gio's second notes. :< he's really taking his time.
all credits goes to : my wild imagination + admin !

good luck for tom p6 ! dont forget to bring money along ~~
