Kinematics - Chapter Summary and Learning Objectives

Kinematics is the study of the motion of objects, and you'll be introduced to several key kinematics concepts in this chapter. Instructors teach you how to solve two-step accelerated motion problems, represent kinematics with graphs and use different diagrams to analyze the motion of objects. You'll study graphs of motion, free fall physics, projectile motion and uniform circular motion. At the end of this chapter, you'll be familiar with:

• Differences between vectors and scalars
• Methods for finding an object's position
• Ways to determine acceleration from the slope of a velocity or a time graph
• Qualitative descriptions of motion depicted in graphs
• Formula for acceleration of gravity
• Use of equations to describe and represent the motion of objects
