# Line integrals

Hi,

I'm greatly puzzled by the physical meaning of line integrals. Based on my understanding, the line inetgral of a scalar function is taking the integral of a function over a curve.

What does this exactly mean? I mean the physical meaning? Just find it hard to absorb and apply the rule of such inetgration.

To add on, there is also line integral of vector field. This again is something which I cant comprehend as well.

Could any kind souls out there explain the concepts to me?
