Introduction The units of the kilogram and Newton are ubiquitous in their uses, but they are used to measure very different aspects associated with the subject of physics. However, in order to know the relationship between the units of kg and Newton, one needs to have an idea of the unit. A unit is stated to be a device that is invariably used in defining the standards of measurements of several physical quantities. It is used for the specified function of forming a relationship of the standard values. In many scientific experiments, the notions of units are essential in positing ... Read More

Introduction Mass and weight both have differences and mass is a scalar quantity but weight is a vector quantity. It is seen that mass and weight are also correlated. The bodies having large mass also have a large weight. It is tough to through a large object because it has a large weight. The weight of a body is directly proportional to its mass. Here the matter is that weight of an object changes with the change of location. Definition of Mass Mass is the quantity of matter possessed by a body. It is called a scalar quantity and it ...

Introduction Mass and Volume are two important aspects of physics. The former mainly defines the amount of matter within an object’s body. The latter one is nothing but the space taken by the object. The main difference between these two aspects is that volume is the geometric value and mass is a physical value of an object. The differences between these two matters say that they have different values and both of the matters have a different state in which they react. What is Mass? Mass mainly defines the quantity of matter within a solid particle. It is considered the ... Read More

Introduction In physics, to measure the physical quantity, different units are generally used. These units also involve some comparison amongst them. In simple diction, the measurement units can be defined by the magnitude of quantity. That is used as a standard for measuring the properties that share some similarities. Based on this particular concept of physics, this tutorial will explain the differences that are found between two units of solid physician quantity measurement. What is Pound? Figure 1: Kilogram and pound The pound has been considered one of the units that are used in order to ... Read More

Introduction Density is the physical quantity which tells us the amount of mass per unit volume. So if I say that the density of iron is 7.874 $\mathrm{gram/centimeter^3}$, it means that 7.874 grams of iron can be placed in 1 $\mathrm{cm^3}$ of volume. And as we know that the molecules of iron are very closely packed and more molecules will be composed in 1 $\mathrm{cm^3}$ of volume. The molecular formula of water is $\mathrm{H_2O}$. It is very important to learn all the properties of water as it is essential for the existence of life on earth. Properties are as follows: ... Read More

Introduction If you take the same size of raw cotton and iron piece in your hands, then you will feel that you are able to compress raw cotton but not the iron piece. This is because the atoms of the cotton are having a lot of gap between them but the atoms of the iron piece are closely packed. So we can say that iron is denser than raw cotton. We know that the atoms or molecules of gasses are much farther than that in solids. So gasses are generally less dense than solid. From here we can conclude that ... Read More

Introduction Time is the concept of "event progression" and is quite hard to understand and define, as its definition is different in the philosophy of every religion. The clock that is based on minutes, seconds and hours measures time. The units of time kept on changing since ancient Sumeria. The famous scientist Einstein proposed the relational "theory of time". Concerning which Aristotle mentioned that there is no "time" apart from the "change". Time mainly follows a universal rhythm of tick-tock. In the "theory of relativity, " this tick-tock rhythm is not mentioned and it has been mentioned that ... Read More

Introduction It is quite difficult to define the aspect of time, but it is referred to as the measurable quantity that displays a series of ongoing and continuous sequences for events. It is noted that measuring time was not something new and from ancient times, several inventions were conducted. As per the records, in ancient Egypt, inventions of sundials were to be found that was before''1500 ``. It needs to be noted that the measurement of time calculated now is quite different from those times in ancient Egypt, with their different parameters. Definition of time Figure 1: Theory ...

Introduction Measurement is an important part of daily life and without that; it is difficult to describe any object or anything. Many kinds of measurement units have been used for a long time and sometimes it varies to place. Many new units also have been introduced with time and need. However, the need for a universal measurement unit was there, to sum up, every other unit, and this process gave birth to the Standard Measurement Unit. What is a Standard Measurement Unit? Figure 1: Conversion between grams and milligrams In today's time, the Standard Measurement Unit is also known as ... Read More

Introduction A proportional relation is found within the temperature and density of an object. As a result of this relation, the changes in the surrounding temperature impact the density of an object. The vibration within particles of an object has created as changes occur within an object. An increase in temperature impacts the overall temperature level. Vibration causes to change in the position of atoms that created heat and as a result, temperature develops. A high temperature is integrally connected to the lower density of an object. Volumes of an object or a solution are also found to lower as ... Read More
