Motion is a universal language. It can have more impact than the actual content being animated. The method you use to move an element in the frame can enhance its meaning. For example, an object that slowly animates across the screen while fading in might provide a sense of mystery and calmness. If the same object flips over and whizzes across the frame, it may express a sense of playfulness, urgency, or even instability. The motion itself can be the message.
