    Cross and Dot product of vectors.

    Someone asked a very interesting question on the role of vectors in Physics. He was curious to know if dot product of vectors is natural but vector product is just syncretism, — that is make shift or unnatural manipulation. Every vector can be resolved into two components. The cosine and sine components (any two vectors…

  • Addendum to Coriolis Force; Definition of Centripetal Force.

    We need to understand first that Force can be categorized into two types. One is called tangential or collinear force. This component of the force is always along the direction of motion and changes speed of an object. It can change direction once the velocity of the object has become zero. Its NOT centripetal force.…

    Coriolis Force; an interesting idea

    Coriolis Force The article is 5.34 K worded.  I have been thinking of writing a basic introduction, on this important physical concept — of, what’s known as a Coriolis force. It is one of the interesting ideas of physics, which does not get as much of a mention perhaps, unless you just happen to know…

    How to add speeds; Galileo and Einstein won’t agree.

    How to calculate the speed of anything, when their speed becomes closer to the speed-of-light.  This article was originally a comment in the linked article;  Why Nothing Moves Faster Than Light. — In order to correct the comment I have made earlier  ” unless something is completely mass-less in its rest-frame ” I also add the following. This…
