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

# Typing Equations on WordPress

Many teachers have asked me how I manage to put up those beautiful equations onto my posts. In this article, I will explain how I use LaTex to create those equations in my posts. LaTex LaTex is a system that scientists used to write their scientific journals. LaTex is huge. According to the LaTex organisation , … Read more Typing Equations on WordPress

# 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

# How a Capacitor Discharge

How does a capacitor work? When a capacitor is connected across a power source, it starts charging up as current flows in the circuit. Initially when the capacitor has not stored any charge, its potential difference is 0 V. As current flows, charges start storing across its plates, and the potential difference increases. The … Read more How a Capacitor Discharge

# 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 and Circular Motion

Why does a orbiting satellite not fall to the Earth? A common misconception among students is that orbiting satellites do not experience gravity. It is argued that since these satellites are not falling to the Earth, they must experience no gravity. This thought is not true because the very action of orbiting around the Earth … Read more Gravitation and Circular Motion

# 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
