Introduction to Circular Motion A circular motion involves an object whose path is curved or circular and is fixed about a point called the centre. A circular motion is always directed towards its centre. However, the object keeps changing its … Read more

Introduction to Centre of Mass Every object having mass is concentrated to its core called the ‘Centre of Mass’. Even a lightweight cotton to a heavy car or let’s say our earth also contains a point where all mass is … Read more

Simply, momentum is a mass in motion. All the moving objects like a moving person, a moving car, a football in motion or even a propelled rocket exhibit a common property called the ‘momentum’. It gives the strength to the … Read more

Introduction to Collisions When we think about collision, a simple picture of two objects striking head to head comes into our mind. For example, two cars meeting head to head will result in an accident. Similarly, a person hitting a … Read more

Transformer is the device for setting electrical energy between two or more circuits. It works on the basis of the principle of electromagnetic induction. Its main use is to increase (step up) or decrease (step down) voltage levels in power … Read more

Unlike a Dynamo, an AC generator is a machine that converts mechanical energy into AC energy. It works on the principle of electromagnetic induction. A conductor moving in a magnetic field experiences an induced electromotive force (EMF). This EMF, when … Read more

A dynamo is one of the major applications of electromagnetic induction. It converts mechanical energy into direct current (DC) electrical energy. It is a traditional electricity generator that generates energy on a huge scale. It played a huge role in … Read more

Electromagnetic induction is the foundation of electromagnetism. Most important discoveries of physics and electrical engineering are on the basis of this phenomenon. It is the process of producing an electromotive force (EMF) and hence current in a conductor by changing … Read more

After the successful discovery of the relationship between electric current and magnetic field, there comes its important application called the motor effect. The mechanism of producing a mechanical motion by the interaction of electrical energy and magnetism is seen in … Read more
