  1. This textbook is intended for a course in introductory physics for students majoring in science or engineering. The entire contents of the book in its extended version could be covered in a three-semester course, but it is possible to use the material in shorter sequences with the omission of selected chapters and sections.

  2. Definitions The fourth state of matter. Plasma is called the fourth state of matter after solid, liquid, and gas. It is a state of matter in which an ionized substance becomes highly electrically conductive to the point that long-range electric and magnetic fields dominate its behaviour.

  3. Class 11 Physics Chapter 3 Motion in a straight line is an important topic as every year many questions come from this chapter in board exams. Thus, the goal of CBSE class 11 physics notes chapter 3 motion in a straight line is to provide detailed step by step information about the topic in a very easy and understandable manner.

  4. • Describe the kinetic theory of gases, including the importance of Brownian motion and diffusion. • Define of r.m.s. velocity of a gas and the mean free path for a gas particle. • Use the expression for the pressure of an ideal gas in terms of its density and mean square speed of molecules to solve problems.

  5. Newton's laws of motion are three basic laws of classical mechanics that describe the relationship between the motion of an object and the forces acting on it. These laws can be paraphrased as follows: A body remains at rest, or in motion at a constant speed in a straight line, unless acted upon by a force.

  6. Q28. State Newton’s first law of motion. Give two examples to illustrate Newton’s first law of motion. Answer: According to Newton’s first law of motion, a body continues to remain in the state of rest or in the state of motion until an external force acts on it. Sliding of a book on the table is an example of Newton’s first law of ...
