NEET Physics Speed & Velocity Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Stopping distance proportional to initial velocity squared | (i) 4 times the original distance |
| (b) Average speed definition | (ii) Total path length divided by time |
| (c) Instantaneous velocity | (iii) Limit of average velocity as time interval approaches zero |
| (d) Average velocity in uniform motion | (iv) Equal to average speed |
a-i, b-ii, c-iii, d-iv
a-ii, b-iii, c-i, d-iv
a-iv, b-i, c-ii, d-iii
a-iii, b-ii, c-iv, d-i
Correct Answer
Detailed Explanation
The stopping distance is indeed proportional to the square of the initial velocity, meaning doubling the velocity increases the stopping distance by a factor of 4. The average speed is defined as the total path length divided by the time interval, and the instantaneous velocity is defined as the limit of average velocity as the time interval approaches zero.
