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 ...

To keep improving your fitness, we tapped experts to reveal how to structure your training for maximum results and how long ...

The theory that gravitons lose energy thru gravitational redshift while traveling against the force of a gravitational field ...

The companies plan to integrate AI into production sites, simulation tools, and electronic design automation for industry.

Morin, L.R.M. (2026) Conjecture on Cosmological Redshift: Action Instead of Velocity, No Need for Dark Energy. Journal of ...

There is a long history of doing physics by imagination. Albert Einstein built his special theory of relativity after imagining himself chasing a beam of light. Erwin Schrödinger gave us a cat that ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their results match “local” measurements but clash with early-universe estimates, ...

This video guides you through the process of calculating the acceleration of a block sliding down an inclined plane with friction. We break down the forces involved and show how to apply Newton’s laws ...

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 ...

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 ...

Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...
