Q1. Which of the following is a vector quantity?
- A.Displacement
- B.Distance
- C.Speed
- D.Time
Answer: A. Displacement
NCERT fact (physics, chapter 'Describing Motion Around Us'): Displacement has both magnitude and direction. Why option A fits - Correct. Distractor analysis: option B) 'Distance' misses the point - Distance is a scalar; option C) 'Speed' is incorrect: Speed is a scalar. Final answer - A) Displacement.
Q2. Which of the following is a scalar quantity?
- A.Speed
- B.Velocity
- C.Displacement
- D.Acceleration
Answer: A. Speed
Eliminate first - option B) 'Velocity' is wrong because A vector; option C) 'Displacement' is incorrect: A vector; option D) 'Acceleration' fails since A vector. That leaves only option A). Confirm with the chapter rule: Speed has only magnitude -> scalar (physics, chapter 'Describing Motion Around Us'). Answer: A) Speed.
Q3. Which quantity tells only how fast a body moves, not in which direction?
- A.speed
- B.velocity
- C.displacement
- D.acceleration
Answer: A. speed
