Is the behaviour of angular displacement different in 2D and 3D motion

Expert Answer:

Dear student,
No. The angular displacement does not change, 

Angular displacement is nothing but the angle through which a body is rotating. In case of the angular displacement the direction of the rotation is important. If the direction is counterclockwise in a circle then the object displaced by a positive 360 degree otherwise it is displaced by a negative 360 degree. If direction is counterclockwise for half circle and then clockwise for the other half circle then the object is displaced by a positive 180 degrees and then a negative 180 degrees thus the total displacement of object is zero. It also measures in terms of the initial and the final positional angle as

ө = өf - өi

Where ө equals angular displacement and өf equals final angular displacement and өi equals initial angular displacement.

Hope this helps.

Thanking you
