To make the fourteenth edition user-friendly for students who are not mathematically inclined, we continue to introduce concepts to be treated mathematically as follows.
First, the concept is defined, as briefly as possible, using words. The definition is then presented, where applicable, as an equation in word form.
And, finally, the concept is expressed in symbolic notation. The level of mathematics in the textbook continues to be no greater than that of general high school math. Appendixes A through G provide a review of the math skills needed to deal with the mathematical exercises in this textbook. It may be helpful for students to begin their study by reading through these seven appendixes. This will help identify and remediate any mathematical weaknesses and thereby build confidence and ability for working the mathematical exercises in the textbook.
Assistance is also offered to students by means of in-text worked Examples and followup Confidence Exercises with answers at the end of the book. However, the relative emphasis, whether descriptive or quantitative, is left to the discretion of the instructor. To maintain a more descriptive approach, the Exercises may be omitted, and the other end-of-chapter sections may be used for assignments.

The concepts of position, speed, velocity, and acceleration are defined and physically interpreted, with applications to falling objects, circular motion, and projectiles. A distinction is made between average values and instantaneous values.
Scalar and vector quantities are also discussed. Also, an interesting Highlight on Galileo and the Leaning Tower of Pisa discusses the status of the tower. Problem solving is difficult for most students.
The authors have found it successful to assign a take-home quiz on several questions and exercises at the end of the chapter that is handed in at the beginning of class. It may save time and be instructive to have students exchange and grade papers as you go over the quiz. This may be followed by an in-class quiz on one of the take-home exercise, for which the numerical values have been changed.
The procedure provides students with practice and helps them gain confidence. If an air track is not available, a 2-in. It will be necessary to have a V groove cut into one edge of the plank to hold a steel ball of about 1-in. The ball will roll fairly freely in the V groove. Also, various free-fall demonstrations are commercially available. General references to teaching aids are given in the Teaching Aids section. An origin or reference point. A scalar has magnitude, and a vector has magnitude and direction.
