Mir We often hear the two words accuracy and precision during the measurement of a physical quantity in an experiment. Most of the students feel that these two terms have the same meaning. But these are much different from each other. In this article, we are going to discuss the concepts and differences between accuracy and … Read more
Suppose you have two carbon resistors of 2 ohms each, but you need 1 ohm resistance to connect in a circuit. What will you do if there are no other sources to collect a resistor of resistance 1 ohm? Again, what will you do if you need 4 ohms to use? Yes, we need to … Read more
Newton’s laws have brought the revaluation in Physics in 19th century. These laws have important roles in science. But, how many laws does Newton have? The answer is that Sir Isaac Newton introduced many laws in many branches of science. Here, we are interested in laws of motion only. We already have discussed three laws … Read more
The three famous laws of motion given by sir Isaac Newton are the basic laws in classical mechanics. These laws describe the rest and motion states of an object. We already have explained Newton’s first law of motion and its importance. In this article, I’m going to explain Newton’s second law of motion with example … Read more
To find the capacitance of Earth we consider that the Earth is a spherical conductor with radius R and total charge Q. In fact, using this assumption one can determine the capacitance of any planet and satellite like Mercury, Mars, Moon, etc. In this article, we are going to find the capacitance of Earth in … Read more
Sir Isaac Newton gave three laws of motion that are applicable to classical particles or systems. The Classical mechanics portion of Physics covers these laws. These laws give concepts of rest and motion of an object and help to find the dynamics of the object or a mechanical system. Do you know what does newton’s … Read more
The term Moment of inertia is used in physics to describe the rotation of an object. The moment of inertia has the same mathematical role in rotational motion as that of the mass in linear motion. But the physical significance of the moment of inertia is different from that of the mass of an object. … Read more
Hypothesis is a predicted theory that satisfies other phenomena but isn’t verified experimentally. Scientist de Broglie gave a such type of theory for the matter particles which plays important roles in Quantum mechanics. In this article, we are going to discuss de Broglie hypothesis for matter waves in quantum mechanics, its explanation and formula and … Read more
Albert Einstein won the Nobel Prize in 1905 for his explanation of Photoelectric effect. There were some failures of classical mechanics to explain this phenomenon. Then Einstein explained it on the basis of quantum theory. In this article, we are going to explore the definition and properties of Photoelectric effect explained by Einstein and will … Read more
The components used in a computer are Input devices, Output devices, a CPU, and Memory units. We can provide electronic data to a computer by using input devices and the output data can be read by using output devices. Memory units store the data in the computer. In other articles, we have discussed Memory units … Read more
