Question 1
A force field in three dimensions is given as \( F(x, y, z) = (y^2, -x^2, 0) \). Determine if this force field is conservative or non-conservative.
💡 Hint: Use curl calculation formulas carefully.
Question 2
Discuss how changes in curl can affect the path taken by a particle moving in a force field and relate it to practical applications.
💡 Hint: Consider real-world instances where paths differ greatly in energy usage.
