Mendeleev's Periodic table simplified the study of elements. As the arrangements of elements showing similar properties were classified into groups, it was very useful in studying and remembering the properties of a large number of elements in a systematic wa..

It is interesting to note that n/p ratio of lighter elements is around one, whereas for heavier metals it is higher. Higher the n/p ratio, more unstable is the element. That is why metals like uranium and polonium are unstable and radioacti..

Newton's First Law of Motion - We shall now study about the exact relation between the force applied and the motion of the object on which the force is applied. This was studied by Sir Issac Newton. He gave the three basic laws of motion concerning objects in moti..

By making a comparative study and assorting the similarities and differences amongst the various varieties of species, organisms can be classified into groups or sets. Taxonomy is a regular branch of science that is involved with the purpose of arranging or grouping organism..

You have studied in the previous chapter about refraction of light by lenses and also about the nature, position and relative size of images formed by lenses. How can these ideas help us in the study of the human eye? The human eye uses light and enables us to see objects aroun..

Kinematics deals with the study of motion without taking into account the cause of motion.Dynamics is concerned with the cause of motion, namely forc..

One of the most important applications of the reflection of sound is oceanographic studies. For this purpose, we use a system called the SONAR. The SONAR is abbreviated form of Sound Navigation and Rangin..
