In this video, we derive the third kinematic equation in one dimension step by step using fundamental definitions of motion. You’ll see how velocity, acceleration, and displacement are mathematically ...
Learn where the centripetal acceleration formula comes from with a clear, step-by-step derivation. This video explains circular motion, velocity direction changes, and the physics behind the equation, ...

Scientists propose a new gravity theory using Friedmann equations. Their model explains the universe’s accelerating expansion ...
The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...
Morin, L.R.M. (2026) Conjecture on Cosmological Redshift: Action Instead of Velocity, No Need for Dark Energy. Journal of ...
The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...
Abstract: Lithium-ion batteries have the characteristics of high energy density, good safety, and long cycle life, so they have been widely used in consumer electronics, military, pure electric ...
Indian mathematician Srinivasa Ramanujan’s century-old formulas for π (pi), once seen as pure curiosities of number theory are now revealing deep links to fundamental physics, potentially helping ...
