Under what condition motion can be circular, rectilinear or zig zag

Answer»

Answer:

A line need not be a straight line…A sphere can have MANY lines drawn over its surface…

A RIVER appears to follow a linear path - but that line is zig-zag…

Rectilinear means along a straight line - the X, Y and Z axes represent the three POSSIBLE rectilinear motions…in three DIFFERENT directions / dimensions.
