Basic difference between slide transition effects and animation effects

Slide transitions are the animation effects that are applied to whole slide whereas animation effects are applied to objects (text, shape, picture etc.) on a slide. For a slide you can have only one transition effect while each object on the slide can have multiple animation effects.

Transition effects appear in PowerPoint slideshow view when slides change from one to the next. Like animation effects we can control the speed of each slide transition effect, and we can also add music or sound. Video below should help you understand the difference:

Transition and animation effects provide visual impact and  grab the audience's attention but when to use them and when not entirely depends upon your content and target audience. It's advisable not to overdo animations or slide transitions and also to stick to one transition effect throughout the slideshow because your audience may find it annoying and distracting. A balanced use of animations and slide transitions can lead to effective presentations which will  keep your audience attentive and awake.
