In this video, we derive the catenary curve using physics and calculus, explaining how a hanging cable reaches equilibrium under gravity. Step-by-step reasoning connects forces, differential equations ...

In this video, we explore five key areas of physics: **Classical Mechanics:** Newton’s second law (F = ma) explains the relationship between force, mass, and acceleration. The law of universal ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

Researchers adapt a novel force measurement technique to uncover the previously unidentified physics at play at the thin air-film gap between water droplets and superhydrophobic surfaces. Microscopic ...
