The mid-1960s saw many dance crazes; one of the most popular ones was a dance called "the jerk." It consisted of holding the arms out in different positions and making thrusting motions with the hips. Though controversial for lewdness at the time, a particularly sexual version of the dance had become popular in Detroit clubs, called the "pimp jerk."
The Capitols had a hit song called Cool Jerk. It was released on July 2, 1966 and was a smash hit, reaching as high as #7 on the Billboard Hot 100 and #2 on the Billboard R&B charts.
Sometimes used by engineers to describe the rate of change in the acceleration of an object. Also used as a unit of rate of change in acceleration equal to a change in acceleration of one foot per second per second in one second: 1 ft/sec3. In this usage, one jerk equals 0.3048 m/s3 or about 0.03108g/sec.
