# Basic quantities in physics - Measurement of Basic Quantities

Furthermore, the SI Unit of force happens to be Newton N.

Whenever non-SI units are discussed, they will be tied to SI units through conversions.

I have been studying various Physics topics for a long time now and have acquired a deep knowledge in many of them.

Description: Answer 1: The representation of physical quantities takes place by physics symbols.

An atomic standard of time, is based on the periodic vibration produced in a Cesium atom.
Some of the clocks developed later are electric oscillators, electronic oscillators, solar clock, quartz crystal clock, atomic clock, decay of elementary particles, radioactive dating etc.
Without standardized units, it would be extremely difficult for scientists to express and compare measured values in a meaningful way.

The units in which they are measured are thus called fundamental units. In this textbook, the fundamental physical quantities are taken to be length, mass, time, and electric current. (Note that electric current will not be introduced until much later in this text.)

quantity itself: (speed) = (length)/(time), one can express energy using base quantities: (1/2)(mass)x(length)2/(time)2. Note that the base quantities are in bold.
