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 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 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 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 ...
Hi readers, I hope you are all well. In this post, we discuss the main topic, equilibrium. Equilibrium can play a fundamental role in the modern and different fields of science. In physics, engineering, or also in chemistry the concept of equilibrium describes and provides information about forces that can be applied to the system. In physics, the equilibrium describes the balanced forces and the torque that can be acted on the system or the body. if the body is at rest or in a motion state, equilibrium explains and provides information about the forces that can act in both types of situations persons.
Equilibrium plays a vital role in understanding the forces and the torque because equilibrium provides stability to the system, also it stabilizes the person who is in the state of re ...
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 friends, I hope you are all well. In this article, we can discuss the scalar or dot products of the vectors. In previous articles, we have discussed vectors and their addition in the rectangular or cartesian coordinate system in depth. Now we can talk about the scalar product of two vectors, also known as the dot product. Scalar or dot products can play an essential role in solving the operation of vector algebra and also they have various applications in numerous fields like computer sciences, mathematics, engineering, and physics.
By doing the scalar or dot products, two vectors are combined when we can do their product, then they produce the scalar quantity which has both magnitude and direction by a single operation in a very efficient way. Simply the scalar and the dot product are ...
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 ...
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 ...
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 ...
