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 Simple Harmonic Motion We find motion in everything in nature. The simple harmonic motion characterizes that type of motion which is oscillating. A simple example is the vibration of guitar strings. We can see a number of back-and-forth … Read more
Introduction to Angular Momentum Angular momentum is one of the key concepts in physics. As like we have linear momentum for linear motion, angular momentum arises when we are talking about the circular motion or a rotational path. It explains … Read more
Introduction to Projectile Motion A projectile motion is the motion of any object that is thrown to the air or released in air. In kinematics, we study the various types of motion, like linear motion and projectile motion. The linear … Read more
Introduction to Circular Motion A circular motion involves an object whose path is curved or circular and is fixed about a point called the centre. A circular motion is always directed towards its centre. However, the object keeps changing its … Read more
Introduction to Centre of Mass Every object having mass is concentrated to its core called the ‘Centre of Mass’. Even a lightweight cotton to a heavy car or let’s say our earth also contains a point where all mass is … Read more
Introduction to Momentum Simply, momentum is a mass in motion. All the moving objects like a moving person, a moving car, a football in motion or even a propelled rocket exhibit a common property called the ‘momentum’. It gives the … Read more
Introduction to Collisions When we think about collision, a simple picture of two objects striking head to head comes into our mind. For example, two cars meeting head to head will result in an accident. Similarly, a person hitting a … Read more
Transformer is the device for setting electrical energy between two or more circuits. It works on the basis of the principle of electromagnetic induction. Its main use is to increase (step up) or decrease (step down) voltage levels in power … Read more
Unlike a Dynamo, an AC generator is a machine that converts mechanical energy into AC energy. It works on the principle of electromagnetic induction. A conductor moving in a magnetic field experiences an induced electromotive force (EMF). This EMF, when … Read more
