This sounds like an herb chopper. Found a picture at www.chefscatalog.com (http://www.chefscatalog.com/catalog/search.aspx?scommand=search&search=herb%2bchopper) It looks just like a draw knife with a rocking blade where you rock it on a cutting board to cut up herbs, or whaever.
It jerks and moves in a somewhat curved line.
At the bottom of it's motion because the gravitational potential energy is zero
Its the Coriolis effect. In fact, the wind is trying to blow straight and the earth is turning under it in a circular motion. The resulting path of the wind on the earth is a curved line.
Linear Motion, reciprocating motion, rotary motion, and oscillating motion
vestibular input, which can be disrupted by the swaying and rocking movements of the boat. This can cause a mismatch between the visual and vestibular information received by the brain, leading to symptoms like nausea, dizziness, and vomiting.
The rocking motion from rocking chairs mimics the motion babies experience in the womb. The familiarity of the movement is thought to be soothing for babies thus putting them to sleep.
a parabolic motion is a motion of an object in a curved path when it is launched...
Gravity.
The curved path is called projectile motion.
A car turning on a curved is known as curvilinear motion.
Curvilinear motion is the motion of an object in a curved path rather than a straight line. It involves changes in both speed and direction as the object moves along the curve. Examples of curvilinear motion include circular motion, parabolic motion, and elliptical motion.

A rocking horse typically consists of a lever (the horse's body), a fulcrum (the rockers on the base), and possibly a wedge (for stability). The rocking motion is created by the lever and fulcrum working together.
