CONCEPT OF EQUATION - LHS & RHS

CONCEPT OF EQUATION - LHS, RHS             Concept of equation can be understood easily by taking an example.  You are given that, your age is exactly half of your father's age, and the sum of your age and your father age is equal to 60, then find out your age and your father's age.           In this example, you are going to equate two values and they are sum of the ages = 60,       On the left hand side, you are going to write as, (X/2)+X=60,                     ...

about physics

   INTRODUCTION TO PHYSICS:     physics is a branch of science which is especially related to measurements.  In our daily life without taking measurements, we can't do any work. For example, when we collect water bottle, we use ask the shop keeper that give me a liter or 2 liter of quantity.  When we go to a cloth store, we use to ask the shop keeper, to give us 2.5 meter length of cloth.  When we go...
