Visualization
The truth is that diagrams for VISUALIZING motion in one dimension are not used whatsoever. But, visualizing it usually helps solving problems about it. In the following diagram, a stick figure boy named Ethan Tan is running. The spaces between the images shows the distance traveled in equal intervals of time.
A: Position is fixed, no velocity, no acceleration. B: Moving with constant velocity, no acceleration. C: Moving with an increasing velocity, positive acceleration. D: Moving with a decreasing velocity, negative acceleration.

Position, Velocity, and Acceleration Graphs

The diagrams to the right represent the value of the position, velocity, and acceleration of an object in motion. AP PHYSICS C ONLYTo get from one graph to the next, take the derivative: position -> velocity -> acceleration.
To go backwards, take the integral: acceleration -> velocity -> position. |
