Gravitational fields are usually illustrated by using radial field vectors.
Gravitational force, however, can be zero if the forces from opposing planets, say, are equal and opposite on some object.
If we look at a graph of gravitational field strength against distance, the gravitational potential is going to be the area under the graph.
The power spectrum of the primordial gravitational waves with ...

The above figure is an example: on the left we show a case where the mechanical energy changes due to non-conservative work.
