NeetVictoryQuestion 1: Equations of Motion
A body starts from rest with a uniform acceleration of 2 m/s². The distance covered in the third second is:
- A 5 m
- B 4 m
- C 9 m
- D 6 m
Answer: A. 5 m
Why: s₃ = a(2n − 1)/2 = 2 × 5/2 = 5 m.

Sample questions on Motion in a Straight Line with answers
8 questions from the practice bank, spread across the chapter's topics. The full set is in the app.
Question 2: Velocity-Time Graphs and Relative Velocity
Two cars approach each other on a straight road at 30 km/h and 40 km/h. The speed of one relative to the other is:
- A 10 km/h
- B 70 km/h
- C 35 km/h
- D 50 km/h
Answer: B. 70 km/h
Why: When two bodies move in opposite directions, the relative speed is the sum of the speeds: 30 + 40 = 70 km/h.
Question 3: Equations of Motion
A ball is thrown vertically upward with a speed of 20 m/s. Taking g = 10 m/s², the maximum height it reaches is:
- A 10 m
- B 20 m
- C 40 m
- D 5 m
Answer: B. 20 m
Why: At the top v = 0, so h = u²/2g = 400/20 = 20 m.
Question 4: Velocity-Time Graphs and Relative Velocity
A velocity–time graph falls linearly from 20 m/s to zero in 10 s. The distance travelled in this time is:
- A 200 m
- B 50 m
- C 100 m
- D 20 m
Answer: C. 100 m
Why: The area of the triangle is ½ × 10 × 20 = 100 m, and the retardation is 2 m/s².
Question 5: Equations of Motion
A ball is thrown upward at 20 m/s from a point on a cliff. Its speed on passing a point 20 m below the starting point is (g = 10 m/s²):
- A 28.3 m/s
- B 14.1 m/s
- C 20 m/s
- D 40 m/s
Answer: A. 28.3 m/s
Why: v² = u² + 2gh = 400 + 2 × 10 × 20 = 800, so v ≈ 28.3 m/s.
Question 6: Velocity-Time Graphs and Relative Velocity
A thief runs at 10 m/s and a policeman 100 m behind chases at 15 m/s. The policeman catches the thief after:
- A 10 s
- B 5 s
- C 6.7 s
- D 20 s
Answer: D. 20 s
Why: The relative speed is 5 m/s, and the gap of 100 m is closed in 20 s.
Question 7: Equations of Motion
A car travels at 40 km/h for the first half of the time and 60 km/h for the second half of the time. Its average speed is:
- A 48 km/h
- B 52 km/h
- C 100 km/h
- D 50 km/h
Answer: D. 50 km/h
Why: For equal time intervals, the average speed is the arithmetic mean.
Question 8: Velocity-Time Graphs and Relative Velocity
The position–time graph of a uniformly accelerated body is:
- A a circle
- B a parabola
- C a straight line
- D a horizontal line
Answer: B. a parabola
Why: x = x₀ + ut + ½at² is quadratic in t.
