The Physics Classroom: Graphs and Ramps Interactive
This tablet-friendly simulation offers a highly interactive way for learners to explore how graphs of position vs. time or velocity vs. time are related to real-world motion. In each exercise, the simulation provides a motion graph. The student's task is to build a ramp with the correct height and incline angles so the motion of the rolling ball matches the target graph. Adjustments can be made until the ramp configuration is an accurate match. Built-in "star" rewards create a game-like environment with incentives to keep going.

The Physics Classroom: Describing Motion with Position vs. Time Graphs
This 3-part tutorial by veteran HS physics teacher Tom Henderson uses multiple graphs to examine the relationship between the motion of an object and the shape of its position vs. time graph. Special attention is given to the meaning of the graph's shape to help beginners differentiate constant velocity from accelerated motion. The slope equation is illustrated in an interactive format allowing for learner self-evaluation.  The tutorial is designed in a manner to help dispel common student misconceptions about the meaning of position.

The Physics Classroom: The Meaning of Shape for a v-t Graph
This tutorial, also written by Tom Henderson, features both graphs and animations to examine how the motion of an object will look on a graph of Velocity vs. Time. Students explore the relationship between position and velocity, positive and negative velocities, the importance of slope in v-t graphs, and how to determine the area on a v-t graph.
