    Matchstick Model (Diamond)Organic and inorganic chemistry has been a very tricky subject for all students. You have to imagine the structure of the molecule. We have been allways doing them on the black boards. Drawing those complex 3 dimensional structures on a 2 dimensional surface can not provide us with ample structural benifits for the students to imagine the structure.

    Why not  make a cheap modelling system that can be made with daily house hold items, which can provide the students with lots of fun and in the same time teach them model making.

  • 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.
