Displacement close displacementA distance measured in a specified direction. is the distance moved in a straight line, in a given direction, from the starting point. Displacement = 24 m east. Velocity ...

Google updated its search engine and Lens tool with new features to help you visualize and solve problems in more difficult subjects like geometry, physics, trigonometry and calculus. The update ...

Newton's Second Law states that force equals mass times acceleration. This can be investigated using a set-up like this one. You can use this set-up to investigate how changing two separate factors, ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Occasionally there are physics lab demonstrations that I think are pretty awesome but that my students just think are "meh." This is one of those cases. The basic idea in this demo, which I used in my ...

Clocks might be far more fundamental to physics than we ever realized. A new theory suggests what we see around us – from the smallest of quantum actions to the cosmic crawl of entire galaxies – could ...
