- A. 2 m/s²
- B. 4 m/s²
- C. 6 m/s²
- D. 8 m/s²
Q2. A body starts from rest and moves with uniform acceleration of 2 m/s². The distance travelled in 5 seconds is:
- A. 10 m
- B. 20 m
- C. 25 m
- D. 50 m
Q3. The area under a velocity–time graph represents:

Detailed Explanations
Q1 Explanation:
Acceleration = (v − u) / t
= (30 − 10) / 5 = 20 / 5 = 4 m/s².
Q2 Explanation:
Using equation of motion:
s = ut + ½at²
u = 0, a = 2, t = 5
s = 0 + ½ × 2 × 25 = 25 m.
Q3 Explanation:
The area under a velocity-time graph gives the total displacement covered during that time interval.
Q4 Explanation:
a = (v − u) / t
= (0 − 20) / 4 = −5 m/s².
Magnitude of retardation = 5 m/s².
Q5 Explanation:
In uniform motion, velocity remains constant and acceleration is zero.

Detailed Explanations
Q1 Explanation:
Fundamental SI units include meter, kilogram, second, ampere, kelvin, mole, and candela.
Newton is a derived unit used to measure force.
Q2 Explanation:
Velocity = displacement / time.
Therefore dimensional formula = [L T⁻¹] or [M⁰ L¹ T⁻¹].
Q3 Explanation:
For multiplication operations, percentage errors are added.
Area = length × breadth.
Total percentage error = 2% + 3% = 5%.
Q4 Explanation:
Strain is defined as change in length divided by original length.
Since it is a ratio of two lengths, it has no dimensions.
Q5 Explanation:
From Newton’s Second Law: Force = mass × acceleration.
Acceleration has dimensions [L T⁻²].
Therefore dimensional formula of force = [M L T⁻²].
