Learn how to calculate the acceleration of a frictionless block on an incline! This video breaks down the physics of motion on an inclined plane, showing you how to apply forces and solve for ...

Make sure your angles are in units of radians (not degrees), where 2π radians = 360 degrees. But after that you will get the value of R (the radius of Earth) in the same units that you measured the ...

If you're a soccer fan, you're familiar with this common sight: A penalty kick is in place, with a "wall" of defenders lined ...

Clocks tick faster on Mars than they do on Earth, in part because Mars experiences less gravitational pull from the Sun. Now scientists have calculated just how much faster -- 477 microseconds, on ...

A new mathematical equation describes the distribution of different fragment sizes when an object breaks. Remarkably, the ...
