SI units and fundamental quantities

General Units and Dimensions

The measuring method is necessary to measure or compare physical quantities in everyday life. Therefore, to measure each of the standard sizes, we choose specific units that are accepted worldwide. Other similar quantities can also be expressed in these units and can be measured accordingly. Physical quantities are measured in terms of unit and are […]

​​Finding Digits of a Number

The smallest mathematical unit of the number system, i.e. the digits of a number, are the symbols that make up the numeral. For example, if there is a number 36, the digits of the number will be 3 and 6, i.e. the number has two digits. You can easily find the digits of a number

Dimensional Formula of Force Constant

Force Constant can be explained by Hooke’s law. This law is named after British physicist Robert Hooke, who lived in the 17th century. Hooke’s law, in its most general form, allows you to determine the relationship between strain and stress for complicated objects based on the intrinsic qualities of the materials they’re composed of. When

Dimensional Formula of Force

Force is one of the fundamental things to exist in nature. It can change the motion of an object. Technically, the force can be defined as a product of mass and acceleration(This is obtained by Newton’s second law). It is denoted by the letter F. Newton was the first-ever person to discover the force, and

Dimension analysis

The powers to which the fundamental units are elevated to obtain one unit of a physical quantity are called the dimensions of that quantity. While writing any dimension we will observe that it has two parts, the first part is a numerical value that expresses the magnitude of the dimension and the second part is

Centre of Mass

Mass refers to the total quantity of matter in a physical body. It is distributed throughout a body and not located at a single point. However, to bring simplicity to physics calculations, it is assumed that all mass is concentrated at a single point within the body. If you can pinpoint the correct position within
