NEETPhysicsMotion in One Dimension

Assertion : Plotting the acceleration-time graph from a given position-time graph of a particle moving along a straight line is possible. Reason : From position-time graph, sign of acceleration can be determined.

Options

  1. AIf both Assertion and Reason are correct and Reason is the correct explanation of Assertion
  2. BIf both Assertion and Reason are correct but Reason is not the correct explanation of Assertion
  3. CIf Assertion is true but Reason is false
  4. DIf Assertion is false but Reason is true

Correct answer

B. If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion

Step-by-step solution

Assertion is correct: From a position-time graph, you can find the velocity (slope). From the velocity-time graph (derived from position-time), you can find the acceleration (slope). So, indirectly, it is possible. Reason is correct: The concavity of the position-time graph gives information about the sign of acceleration. A concave up curve indicates positive acceleration, and a concave down curve indicates negative acceleration. The reason provides a correct statement about position-time graphs and acceleration,
