1. Motion and Velocity Case Study: cars IVHS Melissa Farmer

2. Scenario Illinois Valley Toy Car Company is looking for a new toy car design. The company wants a car that will reach the fastest velocity and that is made out of recycled material. Your job is to come up with a prototype for this company. Illinois Valley Toy Car Company is looking for a new toy car design.

4. Probes Used Motion Probe Motion Probe Students will be measuring the velocity of their created cars Students will be measuring the velocity of their created cars Three prototypes (one being the final) Three prototypes (one being the final) Calculate velocity (change in displacement / change in time). Three trials for each prototype calculating the average for each. Calculate velocity (change in displacement / change in time). Three trials for each prototype calculating the average for each.
