Physical World and Measurement

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

A frame of reference is made up of an abstract coordinate system and a set of physical reference points that are used to fix the coordinate system and standardise measurements within the frame of reference. It is necessary to have a reference point in order to determine the change in position of an object. A

The method of determining the dimensions and units of measurement of physical quantities is known as dimensional analysis.  Dimensional analysis is an excellent method for ensuring that equations are dimensionally correct. We can also utilise dimensional analysis to build credible equations if the quantities are known. It can be used to quantify the size and

Dimensional analysis is the relationship between physical quantities using dimensions and measuring units. Dimensional analysis and its application are crucial because they make no changes in the units, which allows us to do mathematical operations more smoothly. It considers lengths, angles and geometrical qualities, such as flat and straight. The fundamental and derived quantities principle
