The Physics of Simple Harmonic Motion

An object moving in an SHM must obey the relation where  is the displacement and  is the angular frequency of the oscillator.   is related to the frequency of the oscillator by the relation . In this equation, we observe the following: the acceleration of the oscillator is always opposite to the displacement, the magnitude of … Read more The Physics of Simple Harmonic Motion

Simple Harmonic Motion and Circular Motion

Simple harmonic motion is closely related to a uniform circular motion. A real life simple harmonic motion. Review Question 1 Answer the following questions as you watch the first YouTube video(Simple harmonic motion and uniform circular motion). How does the centre of the red cylinder and the green ball relate? At which part of the SHM(left) … Read more Simple Harmonic Motion and Circular Motion

Mathematics of Circular Motion

Angular Displacement The angle which an object moves around a circle is called the angular displacement. This angle is usually expressed in radians. Hence, there are radians in one complete circle. The relationship between the angle in radian and the circle is where  is the angular displacement in radians, and  is the radius of the … Read more Mathematics of Circular Motion

Capacitance

What is a capacitor?   A capacitor is an electrical component that stores charge. It is usually made by having two parallel plates thinly separated by an insulating material. This material is also known as a dielectric. Current flows through an insulator if the voltage across it is sufficient. In a capacitor, the conducting plates … Read more Capacitance

Gravitation – Potential and Potential Energy

Gravitational Potential and Potential Energy Gravitational potential at a point is the amount of work needed to bring a unit mass from infinity to that point. Gravitational potential is defined to be negative since gravity is attractive in nature. A negative potential means that no external work is needed to bring a unit mass from … Read more Gravitation – Potential and Potential Energy

Gravitation – Force and Field Strength

Concept of a Gravitational Field and Force A gravitational field is a region in which a mass experiences a force. A mass, that is present inside a gravitational field experiences a gravitational force. This gravitational field is produced by another mass . The amount of force experienced by the mass is directly proportional to the … Read more Gravitation – Force and Field Strength
