UNIT VECTOR EXPLAINED || MDCAT & ECATE

In this lecture, we explain the concept of Unit Vector in Vector Algebra with clear formulas and geometric interpretation. A unit vector is a vector whose magnitude is 1 and it represents direction only. We derive the formula of a unit vector and express it in terms of vector components and direction cosines. 📌 Topics Covered • Definition of Unit Vector • Representation of unit vector � • Vector in component form • Magnitude of a vector • Unit vector formula • Direction cosines � • Unit vector in terms of i, j, k 📐 Important Formulas |A| = √(Ax² + Ay² + Az²) â = A / |A| A = Ax î + Ay ĵ + Az k̂ â = (Ax/A)î + (Ay/A)ĵ + (Az/A)k̂ â = cosα î + cosβ ĵ + cosγ k̂ This lecture is very helpful for Class 11 Physics, ECAT, MDCAT, Entry Test preparation, and Vector Algebra fundamentals. 🎯 Subscribe for more Physics lectures and concept-based learning. #ecatpreparationUnitVector # VectorAlgebra #PhysicsLecture #ECATPhysics #MDCATPhysics #EntryTestPreparation #VectorsInPhysics #DirectionCosines #PhysicsConcepts #PhysicsTeacher #ecatpreparation #physics #mdcatphysics #physicsconcepts #science
