Dimensional Formula of a Light Year

One light-year is defined as the distance a light beam travels in a year. It is used to communicate galactic distances. It is almost equal to 6 trillion miles (9.7 trillion km). According to the International Astronomical Union, a light-year is a distance travelled by light in a Julian year. The light-year unit first appeared […]

Dimensional Analysis

Dimensional analysis and its applications is the study of connections between physical variables using their units and dimensions of measurement. We utilise dimensional analysis to translate a unit between several forms. We must maintain the same unit to facilitate mathematical operations in science and mathematics.  Dimensional Analysis is often referred to as the factor label

Applications of dimensional analysis:-

Dimensional analysis analyses the correlations between physical quantities based on fundamental properties such as length, mass, time, and electric current, as well as units of measure such as miles VS kilometres or pounds VS kilogrammes. To put it another way, we study two sorts of physical quantities in Physics: basic and derived. Mass, length, amount

Angular Velocity and its Dimensional Formula

Angular velocity is defined as the disclossion of the physical measurements in terms of length, time and mass. Simply put, angular velocity is nothing but the rate of change of angular displacement (i.e., ⍵=  θ/T).  Dimensions – These are mathematical measurements for a particular quantity or measure. These give a simplified understanding of the quantity

Vernier Callipers

Introduction A calliper is a tool for measuring the distance between two opposite surfaces of an item. It might be as basic as a compass with arrows pointing inside or outside. The calliper ends are positioned to fit across the positions to be measured, after which the calliper is withdrawn, and the distance between the

Precision of measuring instruments

Before learning about precision and accuracy, it’s necessary to understand the term “measurement”: – Measurement is necessary to comprehend the external world, and we have developed a sense of measurement over millions of years of life. Measures necessitate the use of tools that provide scientists with a numerical value. The issue here is that the

Least count and significant figures

Introduction When taking a measurement, it’s important to know the significant figures that make up a value. There is always a degree of uncertainty in any experimental results. The major values are the result of a predetermined way of compensating for errors in order to ensure accuracy in measurements and to obtain genuine data. Every
