Textbooks PDF (I-XII) Welcome to the Online Textbooks Section. This online service offers easy access to the NCERT textbooks. The service covers textbooks of all subjects published by NCERT for classes I to XII in Hindi, English and Urdu.
National Council of Educational research and training published physics textbooks for Classes XI and XII, prepared under the chairmanship of Professor t. V. ramakrishnan, F. r.S., with the help of a team of learned co-authors.
Let us see how velocity-time graph looks like for some simple cases. Fig. 2.3 shows velocity-time graph for motion with constant acceleration for the following cases : An object is moving in a positive direction with a positive acceleration. An object is moving in positive direction with a negative acceleration.
NCERT’s efforts to support comprehension of concepts of science and also facilitate inculcation of process skills of science. This manual is complementary to the Physics Textbook for Class XI published by NCERT in 2006 following the guidelines enumerated in National Curriculum Framewor k (NCF)-2005. One of the
We can begin studying thermal properties of matter with definitions of temperature and heat. Temperature is a relative measure, or indication of hotness or coldness. A hot utensil is said to have a high temperature, and ice cube to have a low temperature.

During this course of motion, the path length traversed is OP + PQ = + 360 m + (+120 m) = + 480 m. Path length is a scalar quantity — a quantity that has a magnitude only and no direction (see Chapter 4).
5.1 INTRODUCTION. In the preceding Chapter, our concern was to describe the motion of a particle in space quantitatively. We saw that uniform motion needs the concept of velocity alone whereas non-uniform motion requires the concept of acceleration in addition.
In this chapter, we shall study some common physical properties of liquids and gases. Liquids and gases can flow and are therefore, called fluids. It is this property that distinguishes liquids and gases from solids in a basic way. Fluids are everywhere around us.
