Multiple categories of animation can be used on a single slide to enhance the visual impact and help convey a particular idea or concept. For instance, a slide presenting a process or a timeline can have entrance animations to reveal each element sequentially, emphasis animations to highlight specific details or milestones, and exit animations to signify the completion of the process or timeline. An example of a slide with multiple animations could include an entrance animation of bullets flying in from the left, followed by an emphasis animation of a circle around the key point, and an exit animation of the remaining bullets fading away.
The duration for a transition refers to the amount of time it takes for a slide to transition to the next slide, while the duration for an animation refers to the amount of time it takes for an object to move, appear, or disappear on a slide. The duration for a transition is typically longer than the duration for an animation, as it involves a complete change of slide, while an animation occurs within a single slide.
If a user created two animations set to run simultaneously but set the animations with two different durations, one of the animations would finish before the other, causing an imbalance in the animation timing. Manipulating the durations separately can be useful for certain animation tasks, such as creating a bouncing ball animation, where the duration of the squash and stretch animation is shorter than the duration of the ball's movement. This helps to convey the Principles of Animation, such as timing and spacing, and adds a more natural and fluid motion to the animation.
