Physicists define a physical quantity as a physical property of a material or system that can be measured and defined in terms of its value. A value is a mathematical expression representing a physical quantity that is formed by multiplying a numerical value by a unit of measurement in algebraic notation. n kg is a […]

The metre scale is a device used to measure the length of any item. For instance, the length of a rectangle is 10 metres. The magnitude of the length is 10 in this case, and the unit of length is the metre. 1 metre on the metre scale equals 100 centimetres. Length is measured on

To understand any simple concept, we need to understand the fundamental definition of it. In the world of physics, every physical quantity is compared with its standard unit and that can be defined as measurement. So that brings us to understand what a standard unit is! Any unit which can be easily reproduced and also

Physics and measurements are used in everyday life. Physics is the study of nature and its laws. For example, knowing Newton’s principles of motion and gravitation can explain the moon’s orbit around the earth, an apple falling from a tree and the tides in the sea on a full moon night. Physics is concerned with

There is an axial deformation in the length of a body whenever it is subjected to an axial tensile or compressive load. Longitudinal Strain is the ratio of axial deformation to the original length of the body. Strain Strain is the amount of distortion that an object undergoes as a result of the application of

We convert a unit of measurement into a different unit but with the same property. In physics, we often see questions that ask us to convert between various units. If we take the example of time, we can express it in hours, minutes, and seconds. The distance can be expressed in miles, kilometres, metres, and

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

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

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

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
