(In contrast a scalar quantity has magnitude only - eg, the numbers 1, 2, 3, 4...) This arrow represents a vector. The direction is given by the arrow, while the ...

One of the most important topics taught at the start of introductory physics is the idea of vectors. Students really need proficiency with them if they are to use force and momentum. Just about every ...

Students learn to distinguish between scalar and vector quantities. Introduction to Vectors: Students learn to distinguish between scalar and vector quantities and how to state the magnitude and ...

Scientists have investigated a new two-dimensional form of matter known as Bose glass, which could help physicists study a concept known as many-body localization. Such a concept could help quantum ...
