text: <s>[INST] MAJ Instruction Jerk Units Hi, I'd like to know what Jerk Units refer to. Especially, about % of time, Units per MasterUnit3, % of time-Master Driven. Let me know the definitions of jerk units, please. Environment: Studio 5000 ver33.01_ MAJ, MAM Instruction Best regard Daniel Kim [/INST] Hi Dong-Uk Kim, See this answer only as Information in Physics. Velocity is the movement or rotation speed of your Axis, Drive or whatever. The Unit is distance per time, like meter per second or similar. Acceleration (or Deceleration) is the Change of Velocity. Like how much does the Velocity change per time. So the Unit is Velocity per time, like meter per second² (squared). Jerk is the Change of Acceleration. Like how fast does something accelerate per time. So the unit is Acceleration per time, like meter per second³ (cubic). You can say Acceleration is the derivative of velocity and Jerk is the derivative of Acceleration. As a figurative example think about a car that is towed away: When the towing car starts and the tow rope is tightened, there is a strong jerk in the towed vehicle. You may search for these Terms: S-Curve, reduce Jerk. Jerk Units for a Drive, should be the Unit, at which the Acceleration or Deceleration is allowed to change. Less Jerk is smoother when starting and stopping. \\n </s>
