(i) In animation the screen object is a vector image in animation.
(ii) Using numerical transformations the movement of that image along its paths is calculated for their defining coordinates.
(iii) The least frame rate of at least 16 frames per second gives the impression of smoothness and for natural looking it should be at least 25 frames per second.
(iv) Animations may be in two or three dimensional.
(v) The two dimensional animation, bring an image alive, that occur on the flat X and Y axis of the screen.
