Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process ...

Dive into Python Physics Lesson 12 and learn how energy behaves in a mass-on-a-spring system. This lesson explores kinetic and potential energy, energy conservation, and oscillatory motion, all ...

Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at ...

Math, specifically calculus, is a barrier to many natural sciences, technology and engineering fields. Physics, which is math-heavy, often proves similarly challenging to students who wish to pursue ...

The first semester of an undergraduate physics course invariably spends a lot of time on two big ideas: The momentum principle and the work energy principle. Both deal with forces acting on an object, ...

According to quantum physics, energy can be 'borrowed' -- at least for some time. Energies lower than zero are possible, much like a bank account that can be overdrawn. There are, however, certain ...

Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the plates cause them to push toward each other, as if trying to fill the ...

Try these interactive flashcards based on GCSE physics past papers. By working your way through the flashcards created by experts, you can prepare for your physics exams and make your revision more ...
