Electrostatics(part-1)
Electrostatics:- The Electrostatics deals with all the Phenomena arising out of system of static charges. We are into the domain of physics where interaction takes place between two bodies at a distance. There are two kinds of interaction between two bodies:- One involves the direct contact of two bodies. Other does not involve...
Circular Motion
In previous article , I had covered friction , a very conceptual topic. In this article , we will cover Circular Motion , basically Centripetal & Centrifugal Force. Centripetal and Centrifugal Forces Centripetal Forces:- Any motion in a curved path represents accelerated motion, and requires a force directed toward the...
Friction Explained
Here i am trying to explain friction in lucid manner .This article is pretty complete . If any doubts , do post over here or in the forum. 1. It is the force that opposes relative motion between the two surfaces in contact (contact force) 2. It has been found experimentally that this force is proportional to the normal reaction force...
Puzzle of Centre of Mass Solved
Centre of Mass: Centre of mass is a physical concept which is used to simplify the analysis of motion of a system (continuous or discrete). It is in general defined as a point where the whole mass of the system can be assumed to be concentrated. Generally the concept of centre of mass is used wherever the distribution of mass of the system is...
