UNIT 2 Review: 1-D Motion
Describing Motion with Position-Time and Velocity-Time Graphs:
Review these animations to describe motion using P-T and V-T graphs.
Note: Special thanks to the Physics Classroom for the development of these animations on this page.

The Passing Lane

The lines intersect on the position-time graph, since the red car passes the blue car meaning there is an instant where the the two cars occupy the same postion.

Since the cars never have the same velocity, the lines on the velocity-time graph never cross.
