Solution Summary: The flow of F on C is negative. The vector field F is directed inwards, but the flow is opposite to the orientation of the curve.

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
