How to Do It for a position-time graph, the slope is the velocity. For a velocity-time graph, the slope is the acceleration, and the area under the graph is the displacement. The Drill Use the graph to determine something about the object's speed. Then play "Physics Taboo"; suggest what object might reasonably perform this motion and explain in words how the object moves. Use everyday language. In your explanation, you may not use any words from the list below:
