The movement of an object can be straight or curved. Since moving objects generate a track or line, the same adjectives and emotional responses associated with straight and curved lines can be assigned to straight and curved movement.
Generally, the track created by straight linear movement is associated with these characteristics: direct, aggressive, conservative, ordered, unnatural, and rigid. Tracks created by curved movement can be associated with these characteristics: indirect, passive, confused, pertaining to nature, childlike, romantic, soft, safe, nonlinear, and flexible. These characteristics can create predictable stereotypes, and are only a general guide. Your own feelings about straight and curved lines created by tracks will affect how you use them.
