What is Wheat Stone Bridge? A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component. it was invented by Samuel Hunter Christie in 1833 and improved and popularized by Sir Charles Wheatstone in 1843.Although today […]

This article is about in-depth explanation of newton’s third law of motion. Here in this article I presume that you have a introduction of Newtons first law of motion and Newton’s second law of motion. Now Newtons first law and second law of motion deals with the effect of forces when they acts on a body. First law is about the change in the velocity of the body on the application of unbalanced forces and second law is gives the exact amount of the force needed to produce a given acceleration.

Circular motion is a very important concept in physics. Here in this page I would like to go through the concept of circular motion. You encounter circular motion in your day to day life. Many rides in amusement parks undergoes circular motion. Curves on highway are part of a circle and cars making a tun undergoes circular motion. Merry-go-Rounds in playgrounds offer further examples of uniform circular motion. Now let us learn more about circular motion.
