Mass and Weight


From the beginning of the series, we used the term 'mass' several times. As a beginner, one always confuses mass with weight. Well, there are very distinct differences in between them. Mass and weight have entirely different definition and characteristics.

 Mass

Mass is more like amount of matter, the things it is made of, or the exact quantity of atoms and molecules combined to form a matter. It always occupies space. It is a very important characteristic of matter in order to form the laws of physics. In terms of physics mass defined as the property of matter by virtue of which, matter occupies space. It also determines the strength of gravitational force. SI unit of mass is Kg, and it remains constant everywhere in the space.

 Weight

Whereas weight is more likely a force experienced by any object. We all know that gravity attracts objects. Do we know, what kind of object? Gravity is a property of matter and is associated with mass. It only attracts the object having mass. The objects without mass can’t be attracted by gravity. Can you tell the name of something that doesn’t have mass? Tell us in the comment box. We will discuss these in our advanced episodes. So, gravity attracts objects having mass. This force of attraction is known as weight. In the language of physics weight is defined as the strength of gravitational force on any object. It is calculated by multiplying the mass with acceleration due to gravity (F = gm). Its SI unit is Newton (N) and keep changing at different point in the space. It has its own area of usages and principles. Weight is used in our daily life much more than we have ever observed. Its amazing to observe weight and explore more about how it is so important in our life. See you next time…

Modern Periodic Table

  The modern periodic law The modern periodic law states that the properties of elements are periodic functions of their atomic numbers. This law builds upon the earlier observations made by Dmitri Mendeleev and Julius Lothar Meyer, who organized elements based on their atomic masses. The modern periodic law is an extension of Mendeleev's original periodic law, which stated that the properties of elements are periodic functions of their atomic masses. However, with the discovery of atomic numbers and the realization that atomic number determines an element's position in the periodic table, the modern periodic law replaced the concept of atomic mass with atomic number. According to the modern periodic law, as you move across a period (horizontal row) of the periodic table, the properties of elements gradually change in a periodic manner. Similarly, as you move down a group (vertical column), there is a gradual change in properties with periodicity. The modern periodic la...

Light: Definition and scientific prospective

What is light? Light is a form of electromagnetic radiation that our eyes can detect. It's made up of tiny particles called photons. These photons have both wave-like and particle-like properties, a duality that's one of the intriguing aspects of light. Now, light moves incredibly fast, about 186,282 miles per second (or 299,792 kilometers per second). That's why it seems to reach us almost instantly. Colors come into play when we talk about light. Different colors correspond to different wavelengths of light. When you see a rainbow, you're witnessing the separation of these wavelengths. Light interacts with matter in various ways. It can reflect off surfaces, like a mirror, or refract, bending as it passes through different materials, like glass. Ever wonder why a straw looks bent in a glass of water? That's light bending due to a process called refraction. In a nutshell, light is this incredible blend of waves and particles, speeding through space, bringing us col...
