  • Periodic Table of Elements

    Posted on September 26th, 2014 rudrarup No comments

     

    The Periodic Table of Elements is a tabular display of the chemical elements, organized on a basis of their properties. Elements are presented in increasing atomic number while rectangular in general outline, gaps are included in the rows or periods to keep elements with similar properties together, such as the halogens and the noble gases, in columns or groups, forming distinct rectangular areas or blocks. Because the periodic table accurately predicts the properties of various elements and the relations between properties, its use is widespread within chemistry, providing a useful framework for analysing chemical behavior, as well as in other sciences. 

    Here is a fully functional periodic table that will help you find information about elements.

  • Centrifugal force

    Posted on September 25th, 2014 rudrarup No comments

    When something is going straight, it always keeps going straight unless something else stops it or turns it. If it can’t go straight, then it goes as straight as it can. So when you hit a ball tied to a rope, it tries to go straight away from you. But the rope pulls on it and keeps the ball from going straight. So the ball goes as straight as it can – around the pole in a circle. That’s centrifugal force – the energy of something trying to go straight even though it can’t.

    The Earth is affected by centrifugal force. It is moving, so it tries to keep moving in a straight line. But the gravity of the Sun pulls the Earth toward it, just as the rope pulls the ball. Gravity can’t pull the Earth into the Sun, because the Earth keeps trying to go straight. So the Earth takes a middle road, going in a circle around the Sun.

    Following is a video about centrifugal force.
