Uses and functions

The purpose of making a presentation is to help users convey information accurately and make the audience accept and understand this information more simply and directly. Text, pictures, charts and other contents in PPT serve this purpose, and animation in PPT should also play such a role. According to the needs of the content, choose the appropriate animation to achieve the effect that static content can't achieve. For example, the experimental process in physics teaching courseware can be made with animation effect, and the demonstration effect will be more intuitive and accurate. This application is the unique advantage of animation function, which is irreplaceable by other forms of expression, and can also receive better demonstration effect. However, the application of animation should adhere to the principle of less but better. "Less" means that animation usually does not need to run through, and it is added reasonably where it is needed in PPT.
