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 ...
Hello friends, I hope you are all good. In our previous lecture, we discussed the SI Base Units in detail and today, we are going to discuss the units derived from these base units. In 1960, the International Committee conference was held and they presented the measurement units that are used to measure all quantities worldwide.SI units are used to make accurate and precise measurements.SI units are the set of seven basic units called base units and all other units are derived from these base units and called derived units. A set of seven base units is used to measure the physical quantities but derived units are used to measure the complex quantities other than physical quantities. SI units play an essential role in modern technology and sciences.

Hi, friends I hope you are all well and doing the best in your fields. Today we will discuss the cross or the vector product. In the previous article, we discussed vector quantities, scalar quantities, and the scalar or dot product with their properties, and applications in different fields of science now we can talk about the cross or vector quantities in detail because vectors are used in mathematics, physics, engineering or many other fields. Algebraic operations can also be solved by using the vectors. Vectors are widely used because they can provide the magnitude and direction of a quantity.
The vector product is also known or termed as the cross product. Vector product or in the cross-product are binary vectors or these vectors are perpendicular to each other in the three-dimen ...
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:

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.
Summary.

Hello friends, I hope you are all well and doing your best in your fields. In this post, we can explore the fundamental concept in physics: projectile motion. Projectile motion is the motion of the moving particle or the moving body that can be projected or motion near the earth's surface. Still, the particle can be moved according to the curve path or under the force of gravity and the gravity line. In history first, galileo represented particle motion in the form of projectile motion which can occur in the form of the parabola( the u-shaped curved or mirror-symmetrical in which the particle can be moved) or the motion of the particle which may occur in a straight path in the like if the ball throw downward from upward their motion path is straight.
The detailed or fundamental concept of ...
Hello friends, I hope you are all well and doing your best in your fields. Today we can discuss the fundamental concept of momentum which can play a very crucial role in physics. To understand the motion of the moving object, understanding the concept of momentum is essential. like the velocity, displacement, and momentum are also vector quantities because they can describe the both magnitude and direction of the moving body. Momentum is the product of the mass and the velocity of the objects so it is the vector quantity. The quantity of the motion can be determined through the momentum. Because when the rate of change of force that can be acted on the body is changed, momentum also changes because the rate of change of force is equal to the rate of change of momentum.
In some systems, mo ...
Momentum is a key idea in physics. It’s super important for understanding how things move. It’s a vector quantity, meaning it has direction and magnitude. So, we define it as the mass of an object multiplied by its velocity. Mathematically, momentum (p) can be shown like this:
p=mv
In this formula, (m) stands for mass and (v) for velocity. This simple equation shows us how the mass of an object affects its momentum by showing how fast it’s going.
Historical Background:
The idea of momentum goes way back to the beginnings of classical mechanics, thanks to some great scientists like Sir Isaac Newton & René Descartes. Newton gave us the laws of motion, which helped us understand how momentum stays the same in closed systems. Descartes' thoughts about the conservation of “quantity of mot ...
Hi friends, I hope you are all well. Today we can talk about the dimensions of all physical quantities which include the base quantities and the derived quantities. Dimensions of physical quantities are the fundamental part that helps us understand the physical and natural properties of any physical quantity. In modern science and technology, in engineering, and in different fields of physics where physical quantities units are used, the dimensions of these units help to derive a new formula and are also used in derivations. Dimensions of physical quantities also convey the detail of the types of physical quantity.
Dimension of physical quantities also helps to check the correctness of the equation and the formula that we can derive or use to solve the problems. Dimension of the phy ...
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
