NEET Physics Work-Energy Theorem MCQ Question
In a diagram illustrating the work-energy theorem, a variable force F(x) is applied to an object moving from initial position x_i to final position x_f. Which of the following correctly describes how the work done by the force is determined?
The work done is calculated as the area under the force-displacement curve.
The work done is the product of force and time over which the force acts.
The work done is determined by the final velocity of the object only.
The work done depends on the path taken by the object between x_i and x_f.
Correct Answer
Detailed Explanation
The NCERT context explains that for a varying force, the work done can be expressed as a definite integral of force over displacement, equivalent to the area under the force-displacement curve.
