Transcript of FIZIK FORM 4 (BAB 1)

FIZIK = BOSAN??
adakah anda pasti??
mari kita mulakan penjelajahan ke dunia FIZIK yang sagat membosankan !!
the basic
sains
fizik
kimia
biologi
fenomena
semulajadi
awak tahu tak dari
mana perkataan fizik datang
saya tahu!!
it come from latin word
physica
yang bermaksud science of natural thing
sebelum kita pergi lebih mendalam..
kita perlu tahu perkara asas..
kuantiti fizikal = benda yang boleh di ukur
base quantities
derived quantities
prefix
derived quantities ialah hasil
@
@ kedua2 nya sekali
dari base quantities
vector quantities
scalar quantities
direction
magnitude
length
time
mass
speed
displacement
momentum
acceleration
velocity
pengukuran
vernier callipers
micrometer screw gauge
digunakan untuk mengukur objek bawah 10cm
how to read the scale???
1. cari garisan di belakang "0"
2. cari garisan yang selari/segaris
3. tambahkan hasil 1 dan 2 dalam unit mm
digunakan untuk mengukur objek kecil
how to read the scale???
1. cari ukuran sebelum rotating scale
2. cari ukuran pada rotating scale yang segaris dengan main scale
5.5mm
0.30mm
3. tambahkan hasil ukuran =
5.8mm
sensitivity
error
ability to detect small change in quantity to be measured
the smallest scale is more sensitive!!
1kg
0.1kg
systematic error
random error
incorrect calibration of instrument
zero error
parallax error
when take measurement with incorrect eye position or maybe cause by the environmental factor like light, temperature or other
