What will you learn in CBSE Class 11 Physics Chapter 4 Motion in a Plane?
The chapter consists of around 12 sections, including the ‘Introduction’ and explains concepts related to motion in a plane. It focuses on scalar and vector quantities that are used to determine other quantities like displacement and acceleration.
In the ‘Introduction’ section, students will learn about velocity, position, acceleration, and displacement. These are core concepts used to explain motion in a plane. You can also use them to find solutions to various problems that later appear in the chapter.
The second section of the chapter talks about ‘Scalar’ and ‘Vector’ quantities. Scalar and Vector quantities are the cruces of the chapter as they come in handy for learning other concepts.
In the following sections, you will be learning about the application of vector quantities to find the speed and displacement of an object that moves along a plane. By going over them, you will know how to add, subtract, and multiply vector quantities. You will also know the formulae used in these operations as well as their applications in problems. Apart from this, you will also be learning about the derivation of equations related to vector quantities.
Similarly, other concepts in the chapter include relative velocity in two dimensions, projectile motion and uniform circular motion.
Motion in a Plane is a central concept in Physics that enables you to score higher in the exams. But to do so, you must get enough practice.
But before you do that, there are certain formulae and theorems you should know. The section below gives all the necessary formulae you should be using to solve problems. So, make sure you go through and thoroughly understand them before you head over to the numerical questions.
