### Measurement in physics

1. 1. BY DINI BISMUTIKA RSA1C312007
2. 2. COMPETENCY INTRODUCTIO N MATERIALS CLOSE
3. 3. COMPETENCY INTRODUCTIO N MATERIALS MEASUREMENT AND STANDARD STANDARDS IN PHYSICS TOOLS TO MEASURE SIGNIFICANT FIGURE CLOSE
4. 4.  Identify physical standards in everyday life and include them in the principal standard and the standard of generation.  know the measuring tools.  Understanding the rules of significant figures.
5. 5. In physics you will always be connected with the measurement, standard and units. Do you know what's mean the measurement? On this topic, you can learn a lot about these concepts and should be able to use it in any study physics and in daily.
6. 6.  Measurement is the determination of the scale, dimensions, or capacity, with a standard or unit of measurement  Principal Standard is the standard that the units have been defined in advance.  Derivative Standard is standard units are obtained from the principal standard
7. 7. Principal standard
8. 8. Generation standard Area Volume Velocity Accelaration length x width Length x width x heigth distance : time velocity: : time m2 m3 m/s m/s2
9. 9. TOOLS TO MEASURE FOR LENGTH RULLER MICROMETER SCEW CALIPER
10. 10. balance Tools to measure for mass stopwatch Tools to measure for time
11. 11. ammeters Tools to measure for strong electrical current thermometer Tools to measure for temperature
12. 12. Lux meter Tools to measure for the light intensity Tools to measure for amount of subtance Amount of substances are not measured directly, but by means of measuring the mass of matter in advance.
13. 13. Significant figure is the number obtained from the measurements consist of a significant number that is certain (read the gauge) and the latest figures interpreted or questioned.
