there is no such thing as a gradient for gravitywould you like to tell me how to calculate the gradient, divergence and curl of the gravitational field while you are at it please even though gravity is a
in fact there is no such thing as gradient for any general vector field
you can take the gradient of a muti variable SCALAR field ie input into the function is a vector, and its output is a scalar. And the gradient for that scalar field is defined
to be a vector field, with components that are partial derivatives of the scalar function.
ie if f(x,y,z) =xyz then gradient of f is < yz,xz,xy >
you know dot products and cross products yea?
well the divergence of a vector field is just a dot product between the del operator with the vector field. so the divergence of a vector field is actually a scalar field.
