Non-Example: A non-example of air pressure could be a vacuum.

How do I remember this word?: I remember air pressure, by remembering a weather forecaster. If you ever watch the weather on the news, the weather forecaster, shows an animation in which it points out where the wind is traveling. Sometimes the words “hot” or “cold” are shown.
