Let's start by defining rectilinear motion. In Calculus for the AP® Course, 3e, rectilinear motion is used to describe motion along a line. This concept is consistent with the 2020 Curriculum and Exam Description (CED) which states that "The derivative can be used to solve rectilinear motion problems involving position, speed, velocity, and acceleration." Chapter 2 of the textbook introduces rectilinear motion as an application of the derivative and revisits this topic throughout the text.

Next, let's take a closer look at how calculus can be used to solve rectilinear motion problems. By using the derivative, students can solve problems involving position, velocity, speed, and acceleration. These concepts are essential for understanding straight-line motion and will be tested in the AP® Calculus exams. Therefore, it is essential to help your students practice as much as possible.

To practice solving rectilinear motion problems, students can use Calculus for the AP® Course, 3e. The textbook provides numerous examples that can help students understand the concepts and practice solving problems. Additionally, the textbook is consistent with the College Board's approach, as described in the AP® Calculus AB SAMPLE SYLLABUS #1. This approach supplements the CED and provides additional explanations that can help students understand straight-line motion and its applications.

This guide focuses on content and examples from Calculus for the AP® Course, 3e and can be a valuable resource for educators and their students.

In addition to the textbook, educators can also use AP® classroom resources to help their students practice. Accessing the helpful guide provided by AP® classroom can help students practice solving problems involving rectilinear motion.

In conclusion, understanding straight-line motion is essential for students preparing for the AP® Calculus exams. Rectilinear motion, or motion along a line, can be solved using calculus, specifically by using the derivative. Calculus for the AP® Course, 3e is an excellent resource that provides numerous examples that can help students practice solving problems involving rectilinear motion. Additionally, the AP® classroom resources can be a valuable tool for educators looking to provide additional practice for their students. With these resources, educators can help their students achieve success in their upcoming AP® Calculus exams.
