In every measurement, units and dimensions play a vital role. Every measurement is made up of two components. The first is a number (n), followed by a unit (u). Q = nu. For example, 40 cm is the length of an item. The magnitude of a physical quantity is expressed as a number inversely proportional […]

Fluids, when flowing, offer specific resistance or hindrance. This resistance is termed viscosity. It arises due to the relative motions between two layers of that respective fluid. It can also be thought of as a fluid’s resistance to objects or a measure of the fluid’s thickness when it passes through it. It arises due to

A Reynolds number is a quantity that has no dimension. Reynolds number is used to find out the type of flow pattern as laminar or turbulent during flow through a pipe. Reynolds number is determined by the ratio of inertial forces to the viscous forces. In fluid mechanics the Reynolds number is a basis for

The seven base quantities can be used to express all derived physical quantities. These values are also known as the physical world’s seven dimensions. Square brackets are used to represent them. All dimensions of physical quantities are essential to know. Curious observations and related rigorous experiments are the basis of science. On the other hand,

When the force is applied to a body, it undergoes certain deformations because of that force. Under the effect of that force, the object can contract and expand. And it is the study of the Poisson ratio of a material that will determine its characteristics under an applied force. Calculation of the degree to which

Physical quantities like temperature, volume, time, force, and a variety of other characteristics are surely used to express the principles of physics. Furthermore, some physics symbols are used to represent these numbers. In physics, the symbols for distance may be l, d, or r, for instance. Physics Symbols Language is a tool that humans use

Motion in a Plane is the Motion in two dimensions that requires a two-coordinate system, such as an X-Y coordinate system. An instance of such movement is in the path of a projectile or circular motion. A common example of motion in a plane is that of projectile motion. In terms of physics, an object

The two most essential subjects in statistics are variance and standard deviation. It is a measurement of statistical data dispersion. The degree to which values in a distribution deviate from the average of the distribution is known as dispersion. We have many measures like Range, Quartile Deviation, Mean Deviation and Standard Deviation. The process of

Measurement basics should be reviewed before getting into dimensions and dimensional equations. Seven fundamental (base) quantities may be used to express all physical values from the dimensions of the physical quantities list. These include mass, length, time, temperature, electric current, luminance, and the amount of material. These seven quantities make up the seven dimensions of

CHANGE Change is a process in which the initial and the final properties of a matter differ from each other. During a change, the difference is so specific that it can be measured by using various techniques.  The revolution of earth, twinkling of stars, ripening of fruits, metabolism of body, motion of a vehicle, formation
