Current Electricity Electric current is the rate of flow of electric charge through a conducting medium with respect to time. It is caused by drift of free electrons through a conductor to a particular direction.Charges in Join Our Telegram Channel motion constitute an electric current. Such currents occur naturally in many situations. Lightning is one … Read more current electricity

Electrostatic The basic principle of electrostatics is based on the fact the electric charges attract or repel other charges depending on their relative signs and the law of force is given by Coulomb‘s law. Coulomb’s law states that: The magnitude of the electrostatic force of Subscribe on YouTube interaction between two point charges is directly … Read more Electrostatics

Properties of matter Matter is anything that has mass and takes up space. At a minimum, matter requires at least one subatomic particle, although most matter consists of atoms. The two properties of matter are: • Mass – amount or quantity of matter • Volume – amount of space occupiedphysical properties – inherent characteristics of … Read more Properties of matter

Waves A wave can be described as a disturbance that travels through a medium from one location to another location.It is a disturbance or variation that transfers energy progressively from point to point. It may take the form of an elastic deformation, a variation of pressure, electric or magnetic intensity, electric potential, or temperature. When … Read more waves
Rotational Motion A rotation is a circular movement of an Subscribe on YouTube object around a center (or point) of rotation . A three-dimensional object always rotates around an imaginary line called a rotation axis. If the axis passes through the body’s center of mass, the body is said to rotate upon itself, or spin. … Read more Rotational motion, Gravitation, Simple harmonic motion
Work energy and power Work is said to be done Join Our Telegram Channel when a force applied on the body displaces the body through a certain distance in the direction of force.Mathematically, work is the force-displacement product (for those of you who prefer algebra) W = F x s cos a or the force-displacement … Read more work energy and power
Motion Motion is a change in position of an object with respect to time. Motion is typically described in terms of displacement, distance, velocity, acceleration, time and speed. The branch of physics which deals with the study of motion of material objects is called mechanics. Mechanics is divided into following branches. (i) Statics : Statics … Read more Motion, laws of motion
