dalam chapter 1, kite ade jugak belajar cara untuk mengambil bacaan pada sesetengah alat... antara alat yang ade ialah MICROMETER SCREW GAUGE... jadi, dalam entri kali ni..cikgu akan ajar cara membaca micrometer ini... ini adalah sangat penting lebih-lebih lagi untuk menjawab PAPER 3... JOM BELAJAR syg syg ku... :)
STEP to take the reading: Micrometer Screw Gauge
Turn the thimble until the object is gripped gently between the anvil and spindle.
Turn the ratchet knob until a "click" sound is heard. This is to prevent exerting too much pressure on the object measured.
Take the reading.
Example:
Reading of main scale = 5.5mm Reading of thimble scale = 0.27mm
Actual Reading = 5.5mm + 0.27mm = 5.77mm
LETS DISCUSS here:
the main scale shows that 5.5mm because the thimble scale stop at 5.5
the 0.27mm is taken from the thimble scale because the line 27 stop straight with the main line of main scale.
salam..dulu mase awal2 sem, cekgu kene buat research UTM pasal penguasaan basic concept of physics form4.. bahan kajian cikgu ialah pelajar F5..maklumlah..diorang nak spm.,,, so, supposely master sgt chapter depan... so, saje cikgu nak share research cikgu... N Hasilnye, cikgu dapati masih ramai yang gagal kuasai semua ni..sebab ape?? sebab mase awal2 form4 belaja fizik, kite masih main2 kan?? hihihihi...xpe..perlu tingkatkan usaha lagi!

INI ADELAH SOALAN BASIC YANG SEWAJARNYA DIKUASAI PELAJAR YANG NAK MENGHADAPI SPM...
JADI, CIKGU HARAP ADE YANG NAK MENCUBA JAWAB!!! GoOD LUCk!
Subtopik ini membincangkan kuantiti fizikal . Kuantiti FIZIKAL terbahagi kepada kuantiti asas dan kuantiti terbitan. Kedua-dua kuantiti ini sangat berkait rapat. Bagi menguasai FIZIK, subtopic ini perlu dikuasai dengan SANGAT BAIK!!
Physical Quantities
A physical quantity is a quantity that can be measured.
A physical quantity can be divided into base quantity and derived quantity.
Base Quantities
Base quantities are the quantities that are conventionally accepted as functionally independent of one another.
It is a quantity that cannot be defined in term of other physical quantity.
Dalam bahasa mudahnye: Length Mass Time Temp Current
Derived Quantities
A derived quantity is a quantity that can be derived from base quantity. through multiplying and/or dividing them.
means: to get derived quantity, we need to X or / the base quantity
ok..i prove it...
so, try to master this subtopik.. untuk lagi senang ingat, bole la guna kaedah2 mengingat yang sesuai.
macam cekgu, more to ingat guna singkatan2 setiap unit asas.. LeMasTimeTeCekik..
