11 - U2 Review

This document contains a review sheet for constant velocity particle models with multiple practice problems. The problems involve interpreting position vs. time and velocity vs. time graphs to determine quantities like displacement, average velocity, and distance traveled. They also ask students to draw graphs based on the data provided and describe the motion of objects in various scenarios involving constant or changing velocity.
