Forum:Introductory Physics Homework Help U How to solve cross products in physics problems? Homework Statement I'm solving a physics problem using cross products and I think I might be doing the cross products wrong Homework Equations I'm using the formula: a cross b = (a2b3- a3b2)x + ...
Editorial. Comments on a reader's views on the definition of B in introductory physics through the equation B=F/qm rather than via the Lorentz force equation F=qvxB. Messages conveyed by definitions of concepts; Remarks on basing a definition of B on mythical particles; Phenomena of velocity...
Forum:Advanced Physics Homework Help S What is the relationship between the exterior and cross products? How are the exterior products and the cross products related? Wikipedia says: "The cross product can be interpreted as the wedge product in three dimensions after using Hodge duality to identify...

Remember, each vector, like whatever vector, can be written in terms of its x, y, and z components, I, j, and k. Now when we did this for scalar products and we did this, we didn't really have to calculate the components because all you had to do was just multiply the like ...
Also, using the orientation and metric structure just as for the traditional 3-dimensional cross product, one can in n dimensions take the product of n − 1 vectors to produce a vector perpendicular to all of them. But if the product is limited to non-trivial binary products with vector ...
摘要: Reviews the definition and basic properties of the extended vector cross products. Presentation of a coordinate-free proof of identities that uses only elementary linear algebra; Presentation of another proof employing the tensor product.
While much of the attention on the crosscutting concepts in the NGSS have gone to their coherence across student learning in different STEM disciplines, in this paper, we raise the question of the coherence of student learning of the energy concept within physics itself. Our investigations of tea...
Again, we should do simple cross products in our head: Why? We crossed thexandyaxes, giving usz(ori→×j→=k→, using those unit vectors). Crossing the other way gives−k→. Here’s how I walk through more complex examples:
