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 ...

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

In a new study, physicists at the University of Colorado Boulder have used a cloud of atoms chilled down to incredibly cold temperatures to simultaneously measure acceleration in three dimensions—a ...

Determination of Minimum Surgical Caseloads for Major Oncologic Resections Using a Population-Attributable Fraction Model of Observational Data in Germany In this issue of JCO Oncology Practice, ...

When the greatest mathematician alive unveils a vision for the next century of research, the math world takes note. That’s exactly what happened in 1900 at the International Congress of Mathematicians ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you purchase ...

More than a quarter-century ago, astrophysicists observing distant supernovae made an unexpected discovery: the rate of the universe’s expansion appeared to be accelerating. Now, scientists are ...
