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. Standard The actual physical embodiment of the unit of a physical quantity is known as a standard of that physical quantity. It means it cannot be resolved further in terms of any other physical quantity. It is also known as basic physical quantity.

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. FPS System: foot, pound and second. MKS System: metre, kilogram and second.

Get Started. Hey, I'm Rajan. I'm determined to make your exam score grow. Lets start the free course. Position yourself for success with a comprehensive curriculum and guidance from seasoned mentors.

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.. Other physical quantities derived from the base quantities can be expressed as a combination of the base units and are called derived units. A complete set of units both fundamental and derived units are called a system of units.

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. Any device - physical, conceptual or computational - may be used. Players may score points but can never win - the game is never over. Player score points by discovering a Rule of Nature.

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.

Physicists, like other scientists, make observations and ask basic questions. For example, how big is an object? How much mass does it have? How far did it travel?
