In the last article, I introduced the concept of a “coupled” oscillator, and how its vibrations can be considered as a form of energy transmission between two masses. Coupled oscillators are, indeed, one of the most beautiful concepts in all of physics, perhaps because there is more than one of…

A coupled oscillator consists of two simple harmonic oscillators which are connected, or “coupled” by an intermediary force or potential. In such a system, the oscillation of one particle depends not just on one potential, but two. …

Hello! In today’s article, we’ll be looking at the concept of refraction from an interesting perspective. As we all know, refraction is the change in the direction of travel of a wave when it moves from one medium to another. …

Hi! Today’s article is a little short, but interesting nevertheless! We’re gonna apply L’Hôpital’s rule to find the area of a circle. Let’s begin. The first thing to realize is that a circle can be approximated as a regular polygon with an infinite number of sides. Here’s what I mean.

Math and physics are two subjects so entangled with each other, that its hard to tell which topic relates to one subject or the other. Take today’s topic-stable points. Of course, this applies to math, where stable points can be defined as points on a function where the slope is…

I love physics. Why? Two reasons-one, it allows us to know more about the universe, right from here, our very own planet. All you need is a paper and pen, and you can discover the most fundamental truths about reality! (okay maybe just theoretical physics) But the second reason (and…

Welcome back fellow carbon-based life forms! Last time, we talked about momentum and its conservation. As we saw, it allows us to analyze the interactions between particles just by knowing their initial momentum! Basically, if there are no external forces on a system, its momentum is always conserved. Always. Today…

Hey! Welcome back! Last time we talked about Newton’s laws and forces. That’s dynamics, and as we saw, it becomes really easy to find the acceleration of a body using a free body diagram and applying Newton’s laws. But there is one thing I didn’t talk about, and its no…

Welcome back! Last time we talked about kinematics, or how things move. Now we’ll talk about why things move- forces. They’re the juice of classical mechanics. If you know about all the forces acting on a body, you can predict a lot of things about it. Its trajectory, velocity, everything…
