MEASUREMENT OF PHYSICAL QUANTITIES Definition of quantities : that is something that can be measured and expressed in values. Examples : length, area, volume, speed, weight, temperature, electric current Definition of measurement( to measure) : is an activity to compare a quantity with another quantity that is assigned as a unit

BAHAN AJAR KELAS X SMT : 1 (SATU) BAHAN AJAR KELAS X SMT : 1 (SATU) BY JUARI MATERI4 AUTHOR SK/KD INDIKATOR MATERI LATIHAN TEST X X BRIEF DESCRIPTION OF CONTENT: Quantum number is all number obtained from the measurement result and involving a real number and an estimated number The ruler commonly used at school is a ruler that possess a smallest scale 1mm, is called a mistar-scaled mm. The accuracy of that ruler is a half of the smallest scale.

Micrometer screw has its accuracy level of 0,01 mm Micrometer screw involves a fixed jaw and shifting jaw as shown on the following figure: Vernier Callipers has its accuracy level up to 0,01 cm. Vernier callipers involves fixed jaw and shifting jaw. A long scale cited on the fixed jaw is called a main scale, while a short scale cited on the shifting jaw is called vernier scale as shown on the following Figure:

A B R The amount of Resultant R can be written: Addition of vector using parallelogram method Two vector F 1 and F 2 that possess a decimal point on O are flanking each other of -angle. Vector F 1 can be added by vector F 1 by figuring a parallelogram, F 1 and F 2 become as its sides.

BAHAN AJAR KELAS X SMT : 1 (SATU) BAHAN AJAR KELAS X SMT : 1 (SATU) BY JUARI MATERI9 AUTHOR SK/KD INDIKATOR MATERI LATIHAN TEST X X Addition using polygon or multisides method. The resultant of two vectors or more can be determined by placing one vector to the tip of another vector, then forming a vector from the starting point to the end of the last vector a b R =a + b
