The thumbnail image is of the Whirlpool Galaxy, which we examine in the first section of this chapter. Galaxies are as immense as atoms are small, yet the same laws of physics describe both, along with all the rest of nature—an indication of the underlying unity in the universe. In this text, you learn about the laws of physics. Galaxies and atoms may seem far removed from your daily life, but as you begin to explore this broad-ranging subject, you may soon come to realize that physics plays a much larger role in your life than you first thought, no matter your life goals or career choice. It operates on a vast range of scales involving length, mass, and time. Scientists attempt to describe the world by formulating models, theories, and laws. They utilize orders of magnitudes of numbers to track and compare phenomena occurring on particular scales.

The units that can be expressed independently are called fundamental or base units. For example- mass is expressed in kilogram, length in metre, and time in second respectively are fundamental units. The units for which a combination of the fundamental units is called derived units. The base units for length, mass and time in unit systems are:. CGS System: centimetre, gram and second.

How these systems developed and their use in measuring Length, Mass, Time, and other quantities. Our readers will be able to download pdf of the solutions for all-time access. Chapter 2 Physics Class 11 has 10 major topics which sub-topics providing explanations to the theories explained throughout the chapter. Students are recommended to go through the topics to get an overview of what they will study.

Notes for units and measurements chapter of class 11 physics. Like the video? Physics is a game, physicists are players; the aim is to discover the rules of nature and the playing field is the whole universe.

Physics is a quantitative science, based on measurement of physical quantities. Certain physical quantities have been chosen as fundamental or base quantities. The fundamental quantities that are chosen are Length, Mass, Time, electric current, thermodynamic temperature, amount of substance, and luminous intensity. Each base quantity is defined in terms of a certain basic arbitrarily chosenbut properly standardised reference standard called unit such as metre,kilogram,second,ampere,kelvin,mole,and candela. The units for the fundamental base quantities are called fundamental or base units and two supplementary units in relation to quantities plane angle and solid angle radian, Ste radian..

To measure a physical quantity, we have to find out how many times a standard amount of that physical quantity is present in the quantity being measured. The number thus obtained is known as the magnitude and the standard chosen is called the unit of the physical quantity. Unit The unit of a physical quantity is an arbitrarily chosen standard which is widely accepted by the society and in terms of which other quantities of similar nature may be measured.
