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 ...

Learning the 'effective' notions of static and sliding friction, students of mechanics ... As with many mysteries of physics, this one seems to have quantum origins, with close links with other ...

The questions in this quiz are suitable for GCSE physics students studying electrical charges, charging by friction and electric ... You can revise static electricity by clicking the links below.

As a result, and perhaps counterintuitively, the surface starts sliding more easily, and the relative resistance to motion—the so-called static friction coefficient—decreases. Using a simple ...

Given the surfaces are no longer in touch, they have very little friction, allowing the drops to glide around. In one of the first physics courses at IIT Kanpur, where I teach, new students ...

Fire by friction is a testament to human ingenuity, contributing to the development of early technology and a later understanding of physics, chemistry and heat transfer. Fire by friction relies ...
