Sample practice questions
Easy
1. Which of the following is a vector quantity?
Displacement
Distance
Mass
Time
Answer: Displacement — Displacement has both magnitude and direction, making it a vector quantity, unlike distance, mass and time which are scalars.
Easy
2. What does the LENGTH of an arrow represent when a vector is drawn to scale?
The magnitude of the vector
The direction of the vector only
The scalar equivalent of the vector
Nothing -- only the arrowhead matters
Answer: The magnitude of the vector — When a vector is drawn to scale, the length of the arrow represents the magnitude of the vector, while the direction the arrow points represents its direction.
Medium
3. Give ONE word for a quantity that has magnitude only, with no direction.
Answer: scalar — A scalar quantity has magnitude only, with no associated direction, such as distance, speed, mass or time.
