Question (1)

QN0026207

A student walks 120 m east, then 80 m east again, and finally 50 m west. What is the magnitude of displacement from the starting point?

(A) 250 m
(B) 150 m
(C) 200 m
(D) 90 m

Correct Answer: B

Explanation:

Net displacement = 120 + 80 – 50 = 150 m east.

Question (2)

QN0026208

A cyclist completes one full round of a circular track of radius 35 m. What is the displacement after one complete round?

(A) 220 m
(B) 70 m
(C) 35 m
(D) 0 m

Correct Answer: D

Explanation:

After one complete revolution, the cyclist returns to the starting point, so displacement is zero.

Question (4)

QN0026210

A car travels 180 km in 3 hours and then 120 km in the next 2 hours. Its average speed for the entire journey is:

(A) 50 km h⁻¹
(B) 60 km h⁻¹
(C) 75 km h⁻¹
(D) 80 km h⁻¹

Correct Answer: B

Explanation:

Average speed = Total distance/Total time = (180 + 120)/(3 + 2) = 300/5 = 60 km h⁻¹.

Question (5)

QN0026211

A person moves 100 m north and then 100 m south in 40 s. The average velocity is:

(A) 0 m s⁻¹
(B) 5 m s⁻¹
(C) 2.5 m s⁻¹
(D) 10 m s⁻¹

Correct Answer: A

Explanation:

Net displacement is zero, so average velocity is zero.

Question (6)

QN0026212

An object moving in a straight line covers 30 m, 40 m and 50 m in three successive equal intervals of time. The motion is:

(A) Uniform
(B) Non-uniform
(C) Circular
(D) Oscillatory

Correct Answer: B

Explanation:

Unequal distances covered in equal intervals indicate non-uniform motion.

Question (7)

QN0026213

A train moving at 54 km h⁻¹ accelerates uniformly to 72 km h⁻¹ in 10 s. Its acceleration is:

(A) 0.5 m s⁻²
(B) 1 m s⁻²
(C) 2 m s⁻²
(D) 3 m s⁻²

Correct Answer: A

Explanation:

54 km h⁻¹ = 15 m s⁻¹ and 72 km h⁻¹ = 20 m s⁻¹. Acceleration = (20 – 15)/10 = 0.5 m s⁻².

Question (8)

QN0026214

A bus slows from 25 m s⁻¹ to 10 m s⁻¹ in 5 s. The acceleration is:

(A) +3 m s⁻²
(B) –3 m s⁻²
(C) –5 m s⁻²
(D) +5 m s⁻²

Correct Answer: B

Explanation:

Acceleration = (10 – 25)/5 = –3 m s⁻².

Question (9)

QN0026215

A car moves with constant velocity of 20 m s⁻¹ for 15 s. The displacement is:

(A) 300 m
(B) 200 m
(C) 35 m
(D) 150 m

Correct Answer: A

Explanation:

Displacement = velocity × time = 20 × 15 = 300 m.

The slope of a position-time graph represents:

(A) Distance
(B) Velocity
(C) Acceleration
(D) Time

Correct Answer: B

Explanation:
