When an object is left to vibrate freely, it doesn’t keep swinging or shaking forever. Little by little, its energy gets drained away by things like air resistance, friction, or even internal effects like hysteresis or electromagnetic forces. Because of this energy loss, the vibrations get smaller and smaller over time. This gradual fading of …
A pulley is a machine in which a rope or cable passes back and forth over one or more grooved wheels. In a pulley system, one end of the rope is attached to the load and the other end is pulled in order to move or lift the load. A single pulley has only one …
In physics, there are many types of motion, including linear motion, rotary motion, oscillatory motion, and periodic motion, to name a few. When an object moves while rotating along a circular path, it is known as circular motion. Circular motion is further divided into two categories: uniform and non-uniform circular motion. Today, we’ll focus on …
An object is in unstable equilibrium when a small nudge doesn’t just move it slightly but makes it tumble or slide away completely. Imagine trying to balance a pencil on your fingertip: no matter how careful you are, even a tiny shift will send it wobbling and falling. That’s because the object’s center of gravity …
An object is said to be in neutral equilibrium when, if slightly displaced, it neither returns to its original position nor moves farther away—it simply remains in its new position. In other words, when you give it a gentle push, it doesn’t fight to come back (like stable equilibrium) or topple further (like unstable equilibrium). …
Stable equilibrium is a condition where an object, once slightly displaced from its original position, tends to return to that position on its own. In other words, if you give the object a gentle push or move it a little, it will naturally come back to where it started. Think of it as a “return …
We describe something as fluffy when it is soft, light, and airy in texture or appearance. Most things we consider fluffy are covered with fine hairs, fibers, feathers, or similar materials. To give you a clearer picture, here are some of the most common examples of naturally fluffy things. 1. Down feathers on birds If …
A pentagonal prism is a three-dimensional solid that has two identical, parallel pentagon-shaped bases and five rectangular lateral faces connecting the corresponding sides of the two pentagons. This shape is part of the larger family of prisms, which are defined by having two congruent polygonal bases joined by rectangular sides. A pentagonal prism has 7 …
Magenta is a purplish-pink color that lies between red and blue on the color spectrum. Interestingly, it’s not found as a single wavelength of visible light—instead, our brains perceive magenta when both red and blue light are combined with no green present. In digital color systems like RGB, magenta is created by mixing full-intensity red …
Ever caught a whiff of fresh-baked cookies and instantly smiled? Or walked into a coffee shop and felt like hugging the air? There’s just something magical about good smells. From warm vanilla to sizzling bacon, our noses know how to celebrate the delightful aromas of life. But let’s be honest—not everything in this world smells …
