Physics is the fundamental science that explores the structure of matter and the interactions between its basic constituents across the observable universe.
It delves into both macroscopic and submicroscopic realms, aiming to understand the behavior of objects under various forces and the origins of fundamental force fields such as gravity, electromagnetism, and nuclear forces. At its core, physics seeks to formulate comprehensive principles that unify disparate phenomena.
The subject of physics encompasses numerous branches, each focusing on specific aspects of nature. These branches have evolved to encompass a vast array of phenomena, providing insights into the workings of the physical world.
Among the traditional branches are classical physics, which includes mechanics, optics, acoustics, and electromagnetism.
Each branch of physics contributes to our understanding of the universe, addressing questions ranging from the origins of the cosmos to the behavior of subatomic particles.
Through continuous exploration and experimentation, physicists strive to open the mysteries of nature and uncover the underlying principles governing the physical world.
Introduction to the Feather and Coin Experiment When gravity was not defined, everything was suspected to fall depending on its mass. According to Aristotle, massive objects fall more rapidly than the tiny ones. On studying this concept, Galileo Galilei had … Read more
Introduction to Free Fall While studying force and motion, we have to deal with acceleration, which is a fundament of force. Again, while studying gravitational force, we talk about gravitational acceleration. This fall experienced by the falling object only due … Read more
Introduction to Acceleration Due to Gravity We have studied that every object falls down to earth when thrown upward. This is certainly because of gravity. These objects also fall at a definite rate. This falling of an object under the … Read more
Introduction to Newton’s Law of Universal Gravitation Sir Isaac Newton has done remarkable work in physics, giving a profound theory of gravitation. It associates the gravitational force with masses of two objects and their separation. According to this law, a … Read more
Introduction to Gravitational Force There are four universal forces in nature. Among those forces gravitational force is considered to be the weakest one but has significant effects when the topic is about large-scale structures. It exists between any two objects … Read more
Introduction to Gravitation Gravitation is another type of force acting on two bodies which might have the least impact on the bodies with smaller mass and larger separation between them. However, it turns out to be the strongest one when … Read more
Introduction to Newton’s Laws of Motion Newton’s Laws of Motion are the concepts of Sir Isaac Newton formulated in the 17th century. It consists of three basic laws which describe different forces that act on a body. Thus, the body … Read more
What is a Hysteresis Curve? The word ‘hysteresis’ simply means lagging. In electromagnetism, it is a very useful analysis which suggests the lag of magnetic flux density (B), when magnetic field strength (H) is applied. It is observed that the … Read more
What is the Biot-Savart Law? The Biot-Savart Law is a principle in electromagnetism that deals with the quantitative and qualitative nature of magnetic fields produced by a steady electric current. Hence it provides an empirical relationship between the electric current … Read more
