Grade 10 Physics Unit 1: part 3 Vector Addition | New curriculum | Ris Academy | GlobeDock Academy |

"እዚህ ትምህርት ቀላል ነው!" Welcome to Ris Academy! ⚛️ In this video, we cover *Grade 10 Physics Unit 1, Part2 : Vector Addition* from the Ethiopian New Curriculum. This lesson teaches you the different methods for finding the resultant of two or more vectors! 📚 *What You'll Learn in This Lesson:* What is a Resultant Vector? (The single vector with the same effect as the individual vectors) The Rule: Only vectors of the same kind can be added (force + force, velocity + velocity) Graphical Methods: Triangle Method (Head-to-Tail) Parallelogram Method (Diagonal is the resultant) Polygon Method (For three or more vectors) Special Cases: Vectors in the Same Direction (Add magnitudes) Vectors in Opposite Directions (Subtract magnitudes) Perpendicular Vectors (Use Pythagoras: R = √(A² + B²)) The Component Method (Adding x and y components separately) 🎯 *Learning Competencies:* By the end of this lesson, you will be able to: Add and subtract vectors using graphical methods Find the resultant of perpendicular vectors using the Pythagorean theorem Use the component method to add vectors accurately ⏱️ *Timestamps:* 00:00 – Introduction (Scalars vs. Vectors Addition) 02:38 – What is a Resultant Vector? 03:40 – Methods of Vector Addition: Graphical vs. Analytical 04:54 – Triangular Method (Head-to-Tail Rule) 07:45 – Parallelogram Method (Tail-to-Tail Rule) 10:09 – Polygon Method (Adding More Than Two Vectors) 12:42 – Adding Vectors in the Same Direction 13:42 – Adding Vectors in Opposite Directions 16:33 – Adding Perpendicular Vectors (Pythagorean Theorem) 18:14 – Vectors at Any Angle (Law of Cosines) 19:26 – Vector Subtraction 21:45 – Summary & Outro 🔔 *SUBSCRIBE to Ris Academy for more Grade 10 Physics lessons!* 📱 Join our Telegram for notes & PDFs: [ https://t.me/RisAcademy7 ] *#Grade10Physics #VectorAddition #EthiopianEducation #RisAcademy #PhysicsUnit1 #NewCurriculum #ፊዚክስ #EntranceExam*
