About Separation Measures
A separation measure reports values based on the separation between two points or vertices you select on your mechanism. You can create separation measures of the following types:
• Distance—Measure the absolute value of the distance between two selected points in the mechanism.
• Speed—Measure the rate of change of the separation distance. This value is positive when the points are moving away from each other and negative when moving toward each other.
• Change in speed—Measure the rate of change of the separation speed.
