NEET Physics Work-Energy Theorem Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Work done | (i) Equal to change in kinetic energy |
| (b) Positive work | (ii) Acts against displacement |
| (c) Negative work | (iii) Acts in the direction of displacement |
| (d) Closed path work | (iv) Zero for conservative forces |
a-i, b-iii, c-ii, d-iv
a-ii, b-iii, c-i, d-iv
a-i, b-ii, c-iii, d-iv
a-iv, b-i, c-ii, d-iii
Correct Answer
Detailed Explanation
According to the work-energy theorem, the work done on a particle is equal to the change in its kinetic energy. Positive work occurs when the force acts in the direction of displacement, while negative work occurs when it acts against it. For conservative forces, the work done in a closed path is zero.
