Physics · JEE | WORK, ENERGY AND POWER

हिन्दी

Given below are two statements: Statement I: The work-energy theorem states that the change in kinetic energy of a particle is equal to the work done on it by the net force. Statement II: The work-energy theorem incorporates the complete instantaneous directional and temporal dynamical information contained in Newton's second law in vector form.

  1. A
    Both Statement I and Statement II are incorrect.
  2. B
    Statement I is correct but Statement II is incorrect.
  3. C
    Both Statement I and Statement II are correct.
  4. D
    Statement I is incorrect but Statement II is correct.
View Answer & Solution

Correct answer · Option B

Statement I is correct but Statement II is incorrect.

Explanation

Statement I is the correct definition of WE theorem. Statement II is incorrect because the WE theorem is a scalar integral form and integrates over time/space, losing explicit directional and instantaneous temporal information.
