# Theory of Mechanical Waves Mechanical waves are disturbances that travel through a medium, transferring energy from one location to another. Unlike electromagnetic waves, mechanical waves require a material medium (like air, water, or a solid structure) to propagate. As the wave moves, particles in the medium oscillate around their equilibrium positions, but they do … Read more

# Understanding Static and Dynamic Fluids: Concepts, Equations, and Example Problems Fluid mechanics is the branch of physics concerned with the behavior of fluids at rest (statics) and in motion (dynamics). It addresses numerous phenomena and practical applications, from the circulation of the blood in the body to the design of complex fluid machinery. ## … Read more

# The Working Principle of a Carnot Engine ## Introduction The Carnot engine is the most efficient theoretical heat engine as defined by the laws of thermodynamics. Devised in 1824 by French physicist Sadi Carnot, it serves as a fundamental benchmark for all heat engines. Although a Carnot engine cannot be practically constructed, its principles … Read more

# How to Calculate Work and Energy Understanding the concepts of work and energy is essential in the field of physics. These concepts are not only theoretical but also have practical applications in everyday life. Work is done when a force is applied to an object and the object moves through a distance as a … Read more

### Influence of Gravity on Time Gravity is not only a force that attracts objects toward each other; it also has a profound impact on the fabric of space-time. According to Einstein’s theory of General Relativity, massive objects like planets and stars warp the space-time around them. This curvature of space-time has an intriguing consequence—it … Read more

## Article: Mechanism of the Photoelectric Effect The photoelectric effect is a phenomenon in which electrons are emitted from a material when it absorbs electromagnetic radiation, such as light. This concept was first observed in 1887 by Heinrich Hertz and later explained by Albert Einstein, earning him the Nobel Prize in Physics in 1921. ### … Read more

# Article: Applications of Sound Waves in Technology Sound waves are longitudinal waves that propagate by alternating compression and rarefaction of the medium they travel through—typically air. These waves have found numerous applications in various fields of technology, from medical imaging to communication systems. Here’s how sound waves are harnessed in different technologies: ## Medical … Read more

# Static and Kinetic Friction Forces Friction is a force that opposes the relative motion between two surfaces that are in contact. It plays a critical role in everyday life, allowing us to walk without slipping, cars to move without skidding, and objects to stay put on inclined surfaces. There are two primary types of … Read more

# Article: Problems and Solutions on Rotational Dynamics ## Understanding Rotational Dynamics Rotational dynamics refers to the part of mechanics that deals with the rotation of objects and the forces responsible for it. It is a central concept in classical mechanics, laying the foundation for analyzing the motion of rigid bodies. Several problems in this … Read more

### Explanation of Faraday’s Electromagnetic Law Michael Faraday, an English scientist, made one of the most significant discoveries in the field of electromagnetism in the early 19th century. Faraday’s Law of Electromagnetic Induction, often referred to as Faraday’s Law, relates to the generation of an electromotive force (EMF) in a coil due to a change … Read more
