Grade 11 - Graphical Method of Addition of Vectors in Two Dimensions 📐✏️
📚 Topic: Graphical Method of Addition of Vectors
In physics, vectors can be added graphically using two main methods: the Triangle Law and the Parallelogram Law.
1. Triangle Law of Vector Addition:
Place the tail of the second vector at the head of the first vector.
The resultant vector (sum) is drawn from the tail of the first vector to the head of the second vector. 🔼➕
2. Parallelogram Law of Vector Addition:
Place both vectors with a common starting point.
Draw a parallelogram using the two vectors as adjacent sides.
The diagonal of the parallelogram represents the resultant vector. 🟥➕
🖼️ Visualization: Graphical representation involves drawing vectors to scale using a ruler and protractor, where the length of the vector arrow represents its magnitude, and the direction is given by the angle it makes with a reference axis. 🎯📏
Challenging Questions:
1. Which method involves placing vectors head to tail? a) Triangle Law
b) Parallelogram Law
c) Both methods
d) Neither method
2. What is the resultant vector in the Parallelogram Law? a) The sum of the magnitudes of the two vectors
b) The diagonal of the parallelogram
c) The perpendicular bisector of the parallelogram
d) The average of the two vectors
3. If two vectors are perpendicular, which law can be used to find the resultant vector? a) Triangle Law only
b) Parallelogram Law only
c) Either Triangle or Parallelogram Law
d) Neither method
4. In the graphical addition of vectors, what is the significance of the scale used? a) It makes the drawing more colorful
b) It ensures accurate representation of vector magnitudes
c) It allows vectors to be drawn without considering their magnitude
d) It determines the resultant vector automatically
5. Which of the following is true about the graphical method of vector addition? a) It gives an exact numerical result
b) It is always more accurate than algebraic methods
c) It provides an approximate result with visual understanding
d) It can not be used for vectors with different units
