5 Universitas Jenderal Soedirman Purwokerto Fisika Dasar Mukhtar Effendi Fisika Dasar 5 Arti Fisika: Ilmu yang mempelajari alam dan menyatakannya dengan besaran2 fisis. Hubungannya dg kimia: Kimia mempelajari perubahan yang bersifat tetap, Fisika mempelajari perubahan yang bersifat sementara. Kayu dibakar menjadi arang, abu Besi dibakar membara, tetapi kembali ke ujud semula. Halliday: The main objective of physics is to find the limited number of fundamental laws that govern natural phenomena and to use them to develop theories that can predict the results of future experiments.

9 Universitas Jenderal Soedirman Purwokerto Fisika Dasar Mukhtar Effendi Fisika Dasar 9 However, in October 1983, the meter (m) was redefined as the distance traveled by light in vacuum during a time of 1/ second. In the 1960s and 1970s, the meter was defined as wavelengths of orange-red light emitted from a krypton-86 lamp. Length The basic SI unit of mass, the kilogram (kg), is defined as the mass of a specific platinum–iridium alloy cylinder kept at the International Bureau of Weights and Measures at Sevres, France. This mass standard was established in 1887 and has not been changed since that time because platinum–iridium is an unusually stable alloy. A duplicate of the Sevres cylinder is kept at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. Mass

10 Universitas Jenderal Soedirman Purwokerto Fisika Dasar Mukhtar Effendi Fisika Dasar 10 Time Before 1960, the standard of time was defined in terms of the mean solar day for the year The mean solar second was originally defined as of a mean solar day. The rotation of the Earth is now known to vary slightly with time, however, and therefore this motion is not a good one to use for defining a standard. In 1967, consequently, the second was redefined to take advantage of the high precision obtainable in a device known as an atomic clock. In this device, the frequencies associated with certain atomic transitions can be measured to a precision of one part in This is equivalent to an uncertainty of less than one second every years. Thus, in 1967 the SI unit of time, the second, was redefined using the characteristic frequency of a particular kind of cesium atom as the “reference clock.” The basic SI unit of time, the second (s), is defined as times the period of vibration of radiation from the cesium-133 atom.

12 Universitas Jenderal Soedirman Purwokerto Fisika Dasar Mukhtar Effendi Fisika Dasar 12 Prefiks / awalan untuk satuan SI In 1960, an international committee established a set of standards for length, mass, and other basic quantities. The system established is an adaptation of the metric system, and it is called the SI system of units. (The abbreviation SI comes from the system’s French name “Systeme International.”)
