Sample practice questions
Easy
1. Which of the following is a scalar quantity?
Mass
Displacement
Velocity
Force
Answer: Mass — Mass has magnitude only, with no associated direction, making it a scalar quantity, unlike displacement, velocity and force which are vectors.
Easy
2. What does the DIRECTION an arrow points represent, when a vector is drawn to scale?
The direction of the vector
The magnitude of the vector
The scalar equivalent of the vector
Nothing of significance
Answer: The direction of the vector — When a vector is drawn to scale, the direction the arrow points represents the direction of the vector, while its length represents the magnitude.
Medium
3. Give ONE word for a quantity that has both magnitude AND direction.
Answer: vector — A vector quantity has both magnitude and direction, such as displacement, velocity, acceleration or force.
