Can green theorem be negative

WebFeb 28, 2024 · We can use Green's theorem to transform a double integral to a line integral and compute the line integral if we are provided with a double integral. If the double integral is presented to us, ∬Df (x,y)dA, Unless there occurs to be a vector field F (x,y) we can apply Green's theorem. f (x,y)=∂F 2 ∂x−∂F 1 ∂y. WebWork can be negative! Work is a measurement of energy, so it may seem odd to think that a work can be negative — but it can! Work is how much energy is done by a force over a distance. Suppose we needed to set up ice hockey goal nets. Initially the nets are standing still with zero velocity at the edge of the ice hockey rink.
