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.
Summary.

Hi friends, I hope you all are well. In this post, we will talk about scientific notation. Scientific notation is an essential tool that scientists and engineers can use. Archemdies presented the idea of scientific notation in the 3rd century BC. His work and scientific notation ideas are based on the novel of time, known as place value.Scientific notation ideas have evolved over many centuries but are finally represented by Archimedes. In the 16th or 17th century, mathematicians continued to adopt changes in them and invent many other new notable contributions like Rene Descartes who developed algebraic notation. Scientific notation is a way in which we can express large number values in short form in the form of an exponent or a decimal form.Scientific notation not only simplifies the eq ...
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, today we can discuss the main topic which is Newton's law of motion. Newton's Laws of Motion structure the foundation of traditional mechanics, a part of physical science that depicts the way of behaving of actual bodies. These regulations give a structure to understanding what powers mean for the development of items, from regular encounters to the mechanics of heavenly bodies.
The meaning of Newton's Regulations couldn't possibly be more significant; they offer a straightforward yet significant clarification of how powers interface with issues. These standards are not simply scholarly; they support incalculable parts of our day-to-day routines and mechanical headways. From the working of vehicles and hardware to the direction of satellites, Newton's Regulations give the fund ...
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 this topic we can discuss the main concept of velocity, the velocity time graph. Understanding how things move is key in physics, and velocity-time graphs play a big role in this study. These graphs show how fast an object is going at different times giving us an easy way to look at things like speed changes, distance travelled, and the pushes or pulls involved. For college students, getting good at reading and using these graphs matters a lot. It helps them do well in class and gives them a better grasp of the rules controlling how stuff moves in the world around us.
velocity-time graphs have many uses: they help scientists and engineers model how objects move, guess where they'll be later, and study how different forces affect them. Looking at the gr ...
Hi friends, I hope you are well and doing good in your fields. Today we can discuss the main topic of displacement which plays a fundamental role in the motion of the object. In simple words to study and understand the motion of objects, the concept of displacement is fundamental. When the object can moved it can change its position and cover some distance and displacement. Both quantities represented the quantitative information or description of the motion of an object. Sometimes both quantities of distance and displacement are understood the same but they are not similar to each other because in distance we can describe the motion of an object as the object can be moved from one position to another position but in displacement we can measure the distance with time.To understand the disp ...
Hello everyone! I hope this article will find you in great health. Today, in this article, we will discuss in detail: What is velocity? We will take a look at what exactly velocity is, how it can be measured, what scale has System International (SI) defined to measure the velocity, how many forms of velocity do exist in our surroundings, and what are the real-life applications of this physical quantity?
I will let you guys know about how velocity is a regular part of our daily lives and how it behaves in the environment we are living in. To understand the basic concept we need to have a deeper look at its real-life examples. A detailed discussion on velocity to have a better understanding is provided in the next section. Let’s get started.
