What is an Electric Current? Electric current is defined as the amount of electric charges flowing per unit time through any cross section of a conductor. In electrostatics, electric charge remains at rest. In electricRead More →
What is called an Equilibrium? Equilibrium is the condition of a system or body in which its state of rest or motion is not changing with time. It is called stable equilibrium in studies ofRead More →
What is called a Rolling Motion? Rolling motion is particular type of motion in which a circular or spherical object makes a combination of rotation and translation. For example, if a marble sphere is thrown onRead More →
What are called Capacitor & Capacitance? A capacitor is defined as a combination of two conducting surfaces separated by a non conducting medium such that it can store electric charge. When two conducting surfaces ofRead More →
What is called a “Torque”? Torque is the effect of a force that can cause an object to rotate about an axis. A force produces linear acceleration in an object which is in linear motion. InRead More →
What is Dielectric Constant? Dielectric constant of a medium is defined as the ratio of electrostatic force between two point charges separated by a certain distance in air to the electrostatic force between the sameRead More →
What is called a Projectile Motion? When a particle is thrown in space near the earth’s surface then it moves along a curved path under the influence of gravity, then its motion is called aRead More →
What is Electric Potential Energy? Electric potential energy at a point in the electric field produced by a charge is defined as the work done by an external force in bringing a test charge fromRead More →
What is called “Motion in a Vertical Circle”? When a particle is made to move along a circular path in a vertical plane, the motion is a non uniform circular motion. This is due toRead More →
What is Angular Momentum? Momentum of a moving body is defined as the product of the mass and velocity of the body. It gives an idea about the energy capacity that a moving body possesses.Read More →
What is an Electric Dipole? A pair of two equal and opposite charges separated by a small distance is called an electric dipole. Two equal charges of opposite sign , separated by a small distance constituteRead More →
What is called Electric Field of a Charge? Electric field of a charged body is defined as the region or space around the body within which the influence of its static charge can be feltRead More →
