Hi friends, I hope you are all well. In this post, we can discuss the fundamental concept of collision crucially. Generally, collision is the interaction between two moving bodies because when two bodies interact then they can change their direction during the motion. In physics, we can deal with and understand the motion of the moving bodies so collision is a force that can exert the moving bodies when two or more bodies come in contact for a short period. In moving bodies when two bodies collide they can exert a high force and collide with each other with great force but in their collision, the kinetic energy always remains conserved.
When the collision occurs between the two objects, it can change their velocity because they can change their direction and move quickly. The change in ...
Hi, friends. I hope you are all well. Today we will discuss the SI ( International system of units) in detail. An international committee conference held in 1960 concurred on a set of definitions used to describe the physical quantities. This committee and the founded system are called System International (SI).
SI units are the measurement systems used generally to measure the standards.SI units play a vital role in measuring standard quantities in scientific and technological research.SI units are a set of basic 7 base units from which derived units are defined.SI units also play a vital role in modern metrology and now they become a part of the foundation of modern science and technology.SI units can be categorized into three types: Base unitsSupplementary unitsDerived units

Hi everyone, I hope you are doing well. Today in this post we can discuss significant figures. Significant figures can be evolved and traced a few hundred years ago and they can be developed from time to time according to the precise calculations that can be done in mathematics and modern science and technology.The origin of significant figures can be traced to ancient times in Greece, Egypt, or many other countries where they can be used as Significant figures in calculations or mathematics. With time these significant figures can be used by astronomers, mathematicians, and scientists as well. To measure accurate and precise measurements they can use significant figures with scientific notation. In modern physics and mathematics, significant figures can be used essentially.Now we can star ...
Hi friends, I hope you all are doing well. Today, we can talk about the equations of motion in detail. A basic physics component is the study of motion, which enables us to comprehend how things move and interact with force. A collection of mathematical formulae known as the equations of motion explains the link between an object's velocity, acceleration, displacement, and time.These formulas, which provide the foundation of classical mechanics, are essential for understanding many kinds of motion, including the acceleration of an automobile on a highway, the launch of a ball into the air, and the orbit of a planet around the sun.
Definition and Importance:
When an object's initial state and the forces acting upon it are understood, the equations of motion offer a framework for projectin ...
Hi readers, I hope you are all well. In this post, we can talk about the vectors briefly. Physical quantities can be defined through magnitudes but some physical quantities can be defined through both magnitudes and direction, these types of quantities defined through both magnitude and directional properties are known as vectors, and the quantities that can be explained through magnitude, not with direction are known as scalars. some vectors are force, velocity, displacement, and acceleration. Vectors can explain the direction and magnitude of the quantity but they can't provide their position. It is an essential tool of mathematics that can be used in physics for knowing the direction or magnitude. It cant be used in the 18th century but can be used in the modern era of the 19th century ...
Hello Friends! I hope you all are doing well. Today, I am going to give you a very basic and detailed tutorial on What is Physics? We will also discuss Physics branches, popular Physics books, famous physicians, great inventions in the field of Physics etc. When I was thinking of writing this tutorial on Physics, the first thing came to my mind was "Big Bang Theory" (the TV show, not the event itself). Sheldon was a Physicist & in season finale, he won Nobel Prize in Physics for super asymmetry.
In the 19th century, scientists have divided Physical Sciences in 5 major sections:
Physics.
Chemistry.
Metorology.
Astronomy.
Geology.
Physics is considered as the most important branch of Scie ...
Hello friends, I hope you are all doing well. In this article, we can talk about the precision and accuracy of the measurement. Both of these are used to analyze errors in the measurements which can be calculated. In the era of science and modern technology, accuracy and precision are essential to depict the quality of the measurements. To measure the error in the measurement precision and accuracy techniques can be used because both are used for comprehensive measurement analysis.
To calculate or describe the random errors precision of measurement can be used but if we want to describe the systematic error, accuracy of measurements can be used. Now the details of precision and accuracy, their definition, differences, examples, and their application in different fields are given below:

Hi friends, I hope you are all well. In this article, we can discuss the uncertainty in the measurements which can be measured. In the era of modern science and technology or modern physics, scientists can measure complex quantities and these measurements are not precise and accurate somehow doubt is present in these measurements, these doubts are suspicious known as uncertainty in the measurements. In physics or other fields of technology and engineering measurement is essential to measure or understand the quantity of a material or an object. Because every measurement is correct there are always some doubts or doubtful digits and they are called uncertainty in the measurements.
Now in this article, we can explore the history, definition, quantifying methods, and different techniques tha ...
Hi readers, I hope you are all well. In the previous articles, we discussed different basic physics topics like vectors and others and now we can discuss the major topic torque in this article. Torque can also be called the rotational force or moment of the force. In physics, mechanics, and engineering torque plays a vital role and has a fundamental concept in these fields. Torque is essential to understand or describe the ability of the force of the object to rotate around its axis. The object moves with the linear force but when the object moves around its axis, some pivot point, or the fulcrum with some force then this rotational force of the object is termed as the torque. The word torque is derived from the Latin word "torquere" which means turning or twisting. Torque describes both m ...
The critical value serves as a boundary that defines a specific range where the test statistic acquired during hypothesis testing, is improbable to lie within. The critical value is a benchmark against which the obtained test statistic is compared during hypothesis testing. This comparison helps in deciding whether to reject the null hypothesis or not.
On a graph, the critical value explains the boundary between the acceptance and rejection areas in hypothesis testing. It aids in judging the statistical importance or significance of a test statistic. This article will explain the following basics of critical value:
What is the critical value?
Types of Critical Value.
How to Calculate Critical Value?
Examples of Critical Value.
