For a body moving along a straight line, the following \(v-t\) graph is obtained. According to the graph, the displacement during
1 Uniform acceleration is greater than that during uniform motion
2 Uniform acceleration is less than that during uniform motion
3 Uniform acceleration is equal to that during uniform motion
4 Uniform motion zero
Explanation:
The area under the velocity-time curve is equal to the displacement. So the displacement is less in uniform acceleration than in uniform motion, as the corresponding area is less for the first case.

If a body starts from rest, the time in which it covers a particular displacement with uniform acceleration is
1 Inversely proportional to the square root of the displacement
2 Inversely proportional to the displacement
3 Directly proportional to the displacement
4 Directly proportional to the square root of the displacement
Explanation:
\(s = \frac{1}{2}a{t^2} \Rightarrow \sqrt s \,\alpha \,t\)

Assertion : A body is momentarily at rest at the instant, it reverses the direction Reason : A body cannot have acceleration, if its velocity is zero at a given instant of time.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
When a particle is released from rest position under gravity, then \(v=0\), but \(a \neq 0\).
