Given a velocity field defined by u = 2xy, v = x^2 - 2y, calculate the vorticity and interpret its physical meaning.
💡 Hint: Differentiate u and v!
Consider a flow with angular velocities ω_x = 0.3, ω_y = 0.2, and ω_z = 0.1. Determine if this flow is rotational or irrotational and justify your answer.
💡 Hint: Refer back to the definitions discussed.
