The Shape of a Water Droplet: A Dance of Physics and Nature
Water droplets are a common sight in our daily lives, from raindrops falling gently from the sky to dew forming on leaves. Despite their simple appearance, the shape of a water droplet is a fascinating topic that reveals the intricate forces at play in the natural world. Most water droplets are spherical, but under certain […]
Why Moon is not falling towards Earth surface?
The Cosmic Balance of Motion and Gravity Have you ever looked at the Moon and thought, “Why doesn’t it fall down?” After all, gravity pulls everything toward Earth, right? Surprisingly, the Moon is falling toward Earth—but it never actually hits us. That’s because it’s in a perfect state of continuous free fall, creating a beautiful […]
Why do Astronauts feel weightless at the Space station even if gravity is not zero there?
When we think of astronauts floating freely inside the International Space Station, it’s easy to assume that there’s no gravity in space. But here’s the twist: gravity is very much present—even at the height where the ISS orbits Earth. So, why do astronauts feel weightless? The answer lies in understanding orbital motion and the fascinating […]
NEET Physics Chapter-Wise Weightage 2025
Preparing for the National Eligibility cum Entrance Test (NEET) requires a strategic approach, especially when tackling the Physics section, often considered challenging due to its conceptual depth and problem-solving demands. Understanding the chapter-wise weightage can significantly enhance preparation by allowing aspirants to focus on topics that carry more marks. The NEET Physics syllabus encompasses topics […]
Superfluid: The Most Mysterious State of Matter
When you stir a liquid—like tea in a cup or water in a mug—you see slowing vortices that gradually slow down and stop due to friction between fluid particles. But in a superfluid, something astonishing happens: there is zero friction and zero viscosity. If you stir a superfluid once and return years later, it will […]
