Emphasis Effects are PowerPoint animations that determine how the slide object calls attention to itself while it is on-the-slide. Unlike Entrance and Exit animation effects that allow a slide object to enter or exit the slide area, slide objects with Emphasis animation effects are already within the slide area before they start animating, and continue remaining there even after they have finished animating. Typical Emphasis animation effects are Spin, in which an object spins 360 degrees (and more or less) on its own axis or Grow and Shrink, in which a slide object may increase or decrease its size. You can also apply Emphasis animation effects to text objects so that the fonts or the text colors change. In all, there are 50 or more Emphasis animation effects that PowerPoint provides — however, make sure you use animation only if it adds value to your presentation and helps you explain something better to your audience.
