The line integral of a scalar field measures the accumulation of a scalar quantity along a curve. It is computed by integrating the scalar function over a specified path, essentially summing the values of the function at each point along that path, multiplied by the infinitesimal arc length. This concept plays a crucial role in connecting geometric shapes and physical phenomena, such as finding work done by a force along a trajectory or calculating the mass of a wire with varying density.
