Physical World and Measurement

Introduction: One of the essential engineering tests is the bending or fracture of an object or material, and a characteristic showing that it is young’s modulus of elasticity. It is the unchanged-able fundamental property of a material. This measures how easy the material is to stretch or deform.  In this article, we will get into […]

The resistance of a fluid (liquid or gas) to a change in shape or movement of adjacent sections relative to one another is called viscosity. The term “viscosity” refers to the resistance to flow. The mass of a material substance per unit volume is called Density. Density is calculated using the formula d=M/V, where d

A physical constant, also known as a basic physical constant or a universal constant, is a physical quantity that is universal in nature and has a constant value across time. A mathematical constant, on the other hand, has a fixed numerical value but does not entail any physical measurement. The speed of light in vacuum

Introduction A number is always the measured value when measuring a physical quantity. Using this number only makes sense if the corresponding unit has been given. A measurement’s outcome has a numerical value and an associated unit of measure. Consider the weight of a human body, which weighs three kilograms. In this situation, employing a

The International System of Units (SI), also known as the French Système International d’Unités, is a decimal system of weights and measures that is derived from and extends the metric system of units. It was first used in the United Kingdom in the 18th century. The International System of Units (SI) was established by the

One can write a transpose of a matrix by interchanging the rows into columns or vice-versa. For a matrix where the matrices are equal to the negative of its transpose, the matrix formed is the skew-symmetric matrix. However, the determinant of such a matrix is defined as the skew-symmetric determinant. Suppose, if a matrix A

What do you understand about the S.I. unit? The S.I unit  (abbreviated S.I. from System International, the French name) is a scientific notation for the magnitudes or quantities of significant natural phenomena. The system contains seven fundamental units from which all other units are derived. The SI  unit is a measurement that begins with seven

Introduction  Two types of mathematical values represent object movement in today’s world. The terms force, speed, velocity, and work are frequently used, and each of these quantities are classified as  either scalar or vector quantities. Scalar quantities, such as mass and electric charge, are physical quantities that have only magnitudes. Scalar Definition Scalar quantities are

In physics, scalar (scalar Quantities) are generally physical quantities that are unchanged by changes to a vector space basis. Scalar are often associated with units of measurement.  The change of the vector space basis changes the vector definition according to the basis changes the description of a vector in terms of the basis used but

Agnes Luise Wilhelmina Pickles discovered the concept of Surface tension. She was a self-trained chemist from Germany. Initially, she worked in establishing some modern disciplines in the field of surface science, which mainly describe the physical and chemical properties of solid and liquid surfaces. She discovered this concept with the help of an experiment in
