Grade 11 - Vectors and Types of Vectors 🧭➕➖
📚 Topic: Vectors and Types of Vectors
Vectors are quantities that have both magnitude and direction, unlike scalars, which have only magnitude. Understanding vectors is essential in physics as they are used to describe phenomena like velocity, force, and displacement. 🏹⚙️
Types of Vectors:
Null Vector: A vector with zero magnitude and no direction.
Unit Vector: A vector with a magnitude of one, used to indicate direction.
Equal Vectors: Vectors that have the same magnitude and direction.
Opposite Vectors: Vectors with the same magnitude but opposite directions.
🖼️ Vectors are represented graphically by arrows, where the length represents magnitude and the arrowhead indicates direction. 🎯
Challenging Questions:
1. Which of the following is NOT a vector quantity?
a) Displacement
b) Velocity
c) Time
d) Force
2. What is the condition for two vectors to be considered equal?
a) Same magnitude but different directions
b) Same magnitude and same direction
c) Different magnitudes and different directions
d) Any two vectors with opposite directions
3. If a vector A has components 3 and 4 (written as A = (3, 4)), what is its magnitude?
a) 5
b) 7
c) 1
d) 3
4. What happens to a vector if it is multiplied by a negative scalar?
a) It changes direction
b) It doubles in magnitude
c) It halves in magnitude
d) It remains unchanged
5. If a vector B is given by B = (5, 12), what is the direction of the vector (usually expressed in degrees)?
You can use the inverse tangent function (tan^-1) to find the angle.
