NEET Physics Work-Energy Theorem Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Work done by friction (i) Change in kinetic energy (b) Positive work (ii) Angle between force and displacement is 180° (c) Negative work (iii) Angle between force and displacement is 0° (d) Work-energy theorem (iv) Work done on an object by net force
Choose the correct matching:
a-ii, b-iii, c-i, d-iv
a-i, b-ii, c-iv, d-iii
a-ii, b-iv, c-iii, d-i
a-i, b-iii, c-ii, d-iv
Correct Answer
Detailed Explanation
The work done by friction is negative as it opposes motion, making the angle 180°. Positive work occurs when the angle is 0°, leading to an increase in kinetic energy, which aligns with the work-energy theorem stating that the change in kinetic energy equals the work done by the net force.
