As per your syllabus, the work done by a VARIABLE force F(x) over displacement from x_i to x_f is which?
A∫ F(x) dx from x_i to x_f
BArea only of triangle
CF(x_f) × x_f − F(x_i) × x_i
DF(x_f) − F(x_i)
Answer & Solution
Correct answer: A. ∫ F(x) dx from x_i to x_f
Your syllabus: W = ∫ F(x) dx.
Area under the F vs x curve.
