Introduction to Harmonic Oscillator From classical to quantum mechanics, a harmonic oscillator has established a special place in physics. As previously, we have studied about simple harmonic motion, a harmonic oscillator is also a system that has back and forth … Read more

Introduction to Simple Harmonic Motion We find motion in everything in nature. The simple harmonic motion characterizes that type of motion which is oscillating. A simple example is the vibration of guitar strings. We can see a number of back-and-forth … Read more

Introduction to Angular Momentum Angular momentum is one of the key concepts in physics. As like we have linear momentum for linear motion, angular momentum arises when we are talking about the circular motion or a rotational path. It explains … Read more

Introduction to Projectile Motion A projectile motion is the motion of any object that is thrown to the air or released in air. In kinematics, we study the various types of motion, like linear motion and projectile motion. The linear … Read more

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

Introduction to Momentum 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 … 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
