What is a key consideration when using motions or animations in a presentation?

Using motions or animations in a presentation should always serve a clear purpose and be necessary for enhancing the communication of the content. When animations are purposeful, they can help clarify complex information, draw attention to key points, and facilitate understanding. For example, an animation that visually represents a process can make it easier for the audience to grasp abstract concepts.

Frequent and elaborate animations (as suggested in another choice) can overwhelm the audience, making it difficult for them to focus on the message being conveyed. The goal of a presentation is to communicate effectively, and unnecessary distractions can detract from that objective.

Furthermore, motions or animations should not distract the audience. If they are overly showy or not relevant, they can divert attention away from the primary content, hindering comprehension. Lastly, aesthetics alone do not justify the use of animations; their function in supporting the learning experience is the priority. Thus, purposeful and necessary animations enhance the effectiveness of a presentation rather than simply serving as decorative elements.
