Final answer:
A motion chart relies on the dimension of Time to animate a data set. It helps in visualizing how data points change and can provide insights into trends and patterns by animating the change over the selected timeframe.
Step-by-step explanation:
A motion chart is an advanced visualization tool that adds animation to a data set, usually to display how the data evolves over time. The additional component that motion charts rely on to add this animation is Time (A). By animating the data points as they change over time, motion charts provide a dynamic way to observe trends and patterns within the data.
Understanding Motion Charts
Imagine a motion chart displaying population data for different countries. On such a chart:
- The area under a velocity-time graph (Column A, a.) represents distance traveled over a period of time.
- The gradient of a velocity-time graph (Column A, b.) corresponds to acceleration.
- The area under an acceleration-time graph (Column A, c.) might not directly relate to anything on a motion chart, as it's often more relevant for physical acceleration calculations.
- The gradient of a position-time graph (Column A, d.) indicates the velocity of an object.
When solving problems related to motion charts, both acceleration and distance (as indicated in the Column B chart steps) are key pieces of information that can be derived from different aspects of the data represented.
