This constant acceleration car is a great companion for the constant velocity car. Force & Motion Body styles are subject to change. Pull-Back Car Acceleration Roadster This companion to our popular Constant Velocity Car demonstrates nearly constant acceleration. Simply pull back on the spring-loaded, die-cast roadster then release. Use a motion sensor or tape timer to measure the acceleration. The more you pull it backwards, the greater its acceleration. The open top makes it easy to add mass for explorations of Newton’s Second Law. Size 5.5". P4-1980 Pull-Back Car 12 or more $7 $6 Use a motion sensor or tape timer to measure the acceleration. Constant Velocity Car Here’s an ideal way to pump some excitement into your introductory lesson on velocity and acceleration. Equally appealing to students of all ages, this simple but powerful car provides a visible source of uniform speed. Your students can easily quantify and graph their results, starting them on the road to a conceptual understanding of motion. Requires 2 C batteries, not included. Size 6.5". 44-1090 Car 10 or more 44-1091 C Battery $8 $7 $.60 LESSON IDEA Graphing Constant Velocity Place the Constant Velocity Car on a sidewalk or long piece of paper. Mark its position every 2 seconds for 10 seconds. Record its total displacement (from the start) for each mark. Create a graph of total displacement vs. total time elapsed, and analyze the shape of a Constant Velocity graph.
