Interpreting motion data | Physics | Khan Academy

The same motion data can be presented in various ways, including dot (oil drop) diagrams, position-time tables, and position vs. time graphs. The slope of a position vs. time graph represents the object's velocity: A straight line (constant slope) means the object moved with constant velocity, and a curved line (changing slope) means the object accelerated.

Sections:
00:00 - Position vs. time graph of a constant velocity object
04:18 - Calculating velocity from position vs. time graphs
07:09 - Position vs. time graph of an object speeding up
09:21 - Position vs. time graph of an object slowing down
