Rotational Motion

Principle Magnetic torque is experienced when a current-carrying coil is put in an external magnetic field. The angle through which the coil is deflected due to the magnetic torque effect is proportional to the coil’s current magnitude. Construction  The moving coil galvanometer is formed out of a rectangular coil with numerous turns wound on a […]

An overview The angular acceleration of any system of particles is defined as the sum total of the product of every particle mass and square of distance of each of the particles from the axis of rotation of the entire body. The physical quantity which resists the angular acceleration of the body is known as

The magnitude of a moment of a force acting about a point is proportional to the magnitude of the acting force and the distance between this point and the vector line of the force producing the moment. The moment arm is the distance between the force’s vector line and a chosen point. This article will

If the net external force or torque on a particular point in a system of particles is zero, it is said to be in equilibrium. These points of equilibrium may lie anywhere around the center of mass of the body. For any object in translational motion, external force results in the change in the linear

To understand equilibrium in a rigid body, it is first essential to know what a rigid body is and an equilibrium point.  A rigid body is a substance that has a definite shape that does not change with external force. A rigid body is a system of particles that are each distanced equally, and the

Rotational motion is one of the most commonly observed motions in the universe. The movement of planets around a star and the movement of electrons in an atom are examples of rotational motion. One of the fundamental attributes of a rotating body is its angular momentum. Much like linear momentum that opposes the change in

Angular momentum is an attribute characterised by the rotary inertia of a body or a system of several objects that are moving on an axis that may or may not go via the object or system. Our planet possesses an orbital angular momentum due to its annual motion around the sun and spin angular momentum

Angular momentum is an attribute of a rotational system carrying inertia whose axis may or may not go via the system that is under observation. Our planet possesses an orbital angular momentum due to its annual motion around the Sun and a spin angular momentum due to rotation about its axis every 24 hours. Angular

Introduction A composite system’s total angular momentum is equal to the sum of its individual elements’ angular momenta.  Torque, like force, is defined as the rate of change of angular momentum. The sum of all inner torques in any mechanism is always 0. In other words, the net external torque on any mechanism is always

A physical quantity associated with the system of particles, momentum, is defined as time required to bring the object in motion to rest by application of constant external force. On the basis of types of motion, Momentum is majorly categorized as Linear Momentum and Angular Momentum. Angular Momentum: Brief The rotational analog of linear momentum,
