Physicists have found a clever way to detect the elusive Unruh effect without extreme accelerations. By using atoms that emit light cooperatively between mirrors, acceleration subtly shifts when a ...

We're at the Porsche test track to learn all about acceleration. Unit 2 Segment C: Acceleration and Kinematic Equations We're back at the Porsche test track to learn all about acceleration. Kinematic ...

This is a classic introductory physics problem. Basically, you have a cart on a frictionless track (call this m 1) with a string that runs over a pulley to another mass hanging below (call this m 2).

It's impossible to talk about football these days without talking about the problem of big hits. The giant dramatic collisions between players moving at high speed are at once one of the great ...

Reddit’s r/cars served up a spicy physics refresher this week after one user asked a deceptively simple question: does the ...
