Introduction: Motion in two dimensions, also known as 2D motion, refers to the movement of an object in a plane. This type of motion can be described by using two perpendicular directions, usually horizontal (x-axis) and vertical (y-axis). Examples of 2D motion include the motion of a projectile, a car turning around a corner, or […]

Introduction: Motion in one dimension refers to the movement of an object along a straight line. The study of such motion is crucial as it forms the foundation for understanding more complex forms of motion. In one-dimensional motion, an object can move along the positive or negative direction of a straight line. 1. Basic Concepts […]

Introduction: Electromagnetic Induction is the phenomenon where an electromotive force (EMF) is generated in a conductor when it is exposed to a changing magnetic field. This principle forms the basis for many electrical devices, including transformers, generators, and induction motors. 1. Faraday’s Experiments: Michael Faraday, an English physicist, performed several experiments to discover electromagnetic induction. […]

1. Electric Potential Electric potential at any point in an electric field is the work done in bringing a unit positive charge from infinity to that point, without acceleration. 2. Electric Potential Difference The electric potential difference between two points in an electric field is defined as the work done in moving a unit positive […]

Introduction to Electric Charge Electric charge is a fundamental property of matter that causes it to experience a force when placed in an electric or magnetic field. There are two types of electric charges: Key Properties of Electric Charge: Coulomb’s Law Coulomb’s law describes the electrostatic force between two point charges. The force between two […]
