Momentum
Introduction Momentum is a fundamental concept in physics. It is a vector quantity and is expressed classically as the product of an objects mass and velocity. Definition of Momentum The momentum of an object can be calculated using the formula: where is the mass of the object and is its velocity. Conservation of Momentum One…

Electromagnetic Waves
Introduction Electromagnetic waves are waves of electric and magnetic fields that propagate through space carrying electromagnetic energy. They are solutions to Maxwell’s equations and encompass a wide range of phenomena including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Maxwell’s Equations Maxwell’s equations describe the behavior of both the electric and magnetic…

Impulse
Impulse is a fundamental concept in classical mechanics that describes the effect of a force acting on an object over a short period of time. It is equivalent to the change in momentum of the object and is essential for understanding various physical phenomena, such as collisions and explosions. Definition of Impulse Impulse () is…

Chapter 23: Inertia and Angular Momentum
23.1 Introduction to Rotational Motion In this chapter, we will explore inertia and angular momentum, two fundamental concepts in rotational motion. These concepts are essential for understanding how objects rotate, conserve angular momentum, and how external forces can change an object’s rotational motion. 23.2 Inertia Inertia is the inherent property of an object that resists…

Chapter 22: Momentum, Impulse, and Collisions
22.1 Introduction to Momentum In this chapter, we will explore the concepts of impulse and momentum, two essential principles in the study of mechanics. We will discuss the relationship of these two topics, their role in analyzing collisions, and their relevance in real-life situations. 22.2 Linear Momentum Linear momentum, often simply referred to as momentum,…

Conservation of Momentum
Conservation of momentum is the principle which states that the total momentum of an isolated system remains constant over time, provided no external forces act on the system. This principle is based on the idea that momentum, like energy, cannot be created or destroyed, but can only be transferred between objects. Basic Understanding of Conservation…
