The Boffins' Portal Team A frame of reference is essentially a set of coordinate axes used to define an object’s position in two- or three-dimensional space. It can also be defined as a set of coordinates used to record the position and time of events. There are two types of frames of reference: inertial frame of reference and non-inertial frame …
To describe the motion of an object, we need a frame of reference. A frame of reference is essentially a set of coordinate axes used to define an object’s position in two- or three-dimensional space. It can also be defined as a set of coordinates used to record the position and time of events. The …
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 …
The word dodecagon comes from the Greek words dōdeka meaning twelve, and gon meaning sides. A dodecagon is a two-dimensional geometric shape with twelve straight sides, twelve angles, and twelve vertices. When all the sides and angles are equal, it’s called a regular dodecagon. These 12-sided shapes appear not only in geometry textbooks but also …
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 …
