This interactive homework problem shows a graph of velocity versus time for a moving object and the user is asked to find the final position. The problem is accompanied by a sequence of questions designed to encourage critical thinking and conceptual analysis. It is part of a larger collection of interactive problems developed by the Illinois Physics Education Research Group.

9-12: 2A/H1. Mathematics is the study of quantities and shapes, the patterns and relationships between quantities or shapes, and operations on either quantities or shapes. Some of these relationships involve natural phenomena, while others deal with abstractions not tied to the physical world.

2C. Mathematical Inquiry

9-12: 2C/H3. To be able to use and interpret mathematics well, it is necessary to be concerned with more than the mathematical validity of abstract operations and to take into account how well they correspond to the properties of the things represented.

4. The Physical Setting

4F. Motion

6-8: 4F/M3a. An unbalanced force acting on an object changes its speed or direction of motion, or both.

9. The Mathematical World

9C. Shapes

9-12: 9C/H1. Distances and angles that are inconvenient to measure directly can be found from measurable distances and angles using scale drawings or formulas.

12. Habits of Mind

12B. Computation and Estimation

6-8: 12B/M3. Calculate the circumferences and areas of rectangles, triangles, and circles, and the volumes of rectangular solids.
