Absolute And Relative Motion
January 12, 2019
An absolute motion is a motion to move a taught position without affected by the previous motion.
In actual practice, there is no absolute motion, since an arbitrary set of axes or planes is always required to define a motion. However, the earth can be taken as a fixed reference plane and all motions relative to it are termed as absolute motions.
Motion of a body with respect to another fixed body is called absolute motion.
Relative Motion :-
A relative motion is a motion to move by a taught distance from the current position. Since a relative motion sets its reference to the current position of the result of executing the previous motion command, the previous motion command affects the motion.
