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, ...

In 1927, Heisenberg putforth uncertainty principle to the world of quantum physics. It stated that, more precisely the position is determined, less precisely momentum could be determined. The ...

Grover Washington Jr. Middle School teachers Alison Barnes and Gwen Huett don sumo suits to explain basic physics to fifth grade students as part of the "FMA Live! Forces in Motion" performance on ...

It’s a fundamental principle of physics that particles with opposite charges attract each other, while those with the same charge repel. But now, scientists at the University of Oxford have found that ...

Consider the following physics problem. An object with a mass of 1 kg and a velocity of 1 m/s in the x-direction has a net force of 1 Newton pushing on it (also in the x-direction). What will the ...

DR. DANIELL'S “Principles of Physics” is known to be an excellent systematic treatise on physical science, setting forth fundamental principles in a sound and scientific way. In the volume now under ...
