NCERT Solutions for Class 9: Points to Remember

We have provided some important points that are covered in NCERT Class 9 Science, Maths and Social Science to help students in their exam preparations. Refer to the list below:

NCERT Class 9 Science


  • Matter:
    • Anything which has mass and occupies some space is called matter
    • Solid, liquid and gas are not substances but three different states of the same substance.
  • Laws of Chemical Combination :
    • The combination between the elements is governed by the laws of chemical combination.
    • The law of conservation of mass was given by Lavoisier.
    • The law of constant proportions was given by Louis Proust.
    • The law of constant proportions is applicable only to pure chemical compounds.


  • Cell Theory:
    • The cell theory was proposed by Schleiden and Schwann, which states, “All the plants and animals are composed of cells, and the cell is the basic unit of life”.
    • Rudolf Virchow further expanded the cell theory by suggesting that all cells arise from pre-existing cells.
  • Classification and Evolution:
    • The variation among living organisms with respect to their external and internal structures, genetic characteristics, feeding habits, habitats and behaviour is called biodiversity.
    • Charles Darwin first described the idea of evolution in 1859 in his book, The Origin of Species.


  • Force:
    • Force generally denotes push or pull.
    • Force can (a) produce motion, (b) stop motion, (c) change the direction of motion, and (d) change the dimension in a body.
    • Force is defined as an external agent which changes or tends to change the state of rest or uniform motion of a body or changes the direction of the body or deforms the body.
  • Mass and Weight:
    • Mass is the amount of matter contained in a body. It is a scalar quantity, and its SI unit is the kilogram (kg).
    • Weight is the pull exerted on a body by the Earth. It is defined as the product of mass (m) and acceleration due to gravity (g). It is a vector quantity, and its SI unit is the newton.
    • The mass of an object is constant and does not change from place to place whereas its weight depends on its location because g depends on location.

NCERT Class 9 Maths

  • Number Systems
    • Natural Numbers: These are the counting numbers (1, 2, 3, etc.).
    • Whole Numbers: The set of numbers that includes all natural numbers and the number zero are called whole numbers. Whole numbers are also called Non-negative integers.
    • Prime Numbers: A natural number larger than 1 is a prime number if it does not have other divisors except for itself and 1. (The lowest prime number is 2. 2 is also the only even prime number. The lowest odd prime number is 3.)
  • Standard Form of Linear Equation in Two Variables:
    • An equation of the form ax + by + c = 0, where a, b, and c are real numbers such that a and b are not zero, is called a linear equation in two variables.
  • A linear equation in two variables has infinitely many solutions.
  • Axioms and Theorems:
    • There are three basic terms in geometry, namely “Point”, “Line” and “Plane”. It is not possible to define these three terms precisely. So, these are taken as undefined terms.
    • Axioms or postulates are the basic facts which are taken for granted without proof.
    • Theorems are statements which are proved through logical reasoning based on previously proved results and some axioms.
