🌍 Motion in a Plane – Class 11 Physics (NCERT) Motion in a Plane deals with movement in two dimensions, using the concepts of vectors and projectile motion . This is the second part of kinematics after motion in a straight line. 📘 Key Concepts Scalars: Quantities with magnitude only (e.g., speed, mass) Vectors: Quantities with both magnitude and direction (e.g., velocity, displacement) Vector Addition: Using triangle or parallelogram law Resolution of Vectors: Splitting a vector into components along x and y axes 🧮 Basic Vector Formulas Resultant of two vectors: R = √(A² + B² + 2ABcosθ) Component form: A = A x î + A y ĵ Magnitude: |A| = √(A x ² + A y ²) Direction: θ = tan⁻¹(A y /A x ) 🎯 Projectile Motion When an object is thrown at an angle, it follows a curved path called a projectile . It is a 2D motion with horizontal and vertical...
