NCERT CLASS: 11, CHAPTER NO. 1, Units and Measurements 

NCERT Grade 11 Physics Chapter 3: Motion in a Plane — Micro-Learning Modules

Part 1: Scalars, Vectors, and Multiplication

• Focus: Difference between scalars and vectors, position and displacement vectors, and multiplying vectors by real numbers.

• Goal: Understand the basic properties of 2D physical quantities.

Part 2: Addition and Subtraction of Vectors (Graphical)

• Focus: Triangle law, Parallelogram law, and Polygon law of vector addition.

• Goal: Visualize how vectors combine in a plane.

Part 3: Resolution of Vectors and Analytical Addition

• Focus: Rectangular components (Unit vectors i and j), Magnitude, and Direction calculation.

• Goal: Learn the mathematical "splitting" of vectors for easier calculation.

Part 4: Motion in a Plane with Constant Acceleration

• Focus: Velocity and acceleration in 2D, and kinematic equations for a plane.

• Goal: Bridge the gap between 1D motion and 2D paths.

Part 5: Relative Velocity in Two Dimensions

• Focus: The "Rain-Man" and "River-Boat" problems.

• Goal: Understand how velocity appears from different moving frames.

Part 6: Projectile Motion

• Focus: Path of a projectile (Parabola), Time of flight, Maximum height, and Horizontal Range.

• Goal: Master the most important application of 2D motion in exams.

Part 7: Uniform Circular Motion

• Focus: Angular velocity, Centripetal acceleration (v^2/r), and Frequency.

• Goal: Understand motion where speed is constant but direction changes.
