## AP Physics 1: Kinematics - Chapter Summary and Learning Objectives

Use this kinematics chapter to explore the properties associated with an object in motion and make sense of the lines, diagrams and graphs used to represent them. Lessons include plenty of illustrations and sample problems you can use to practice solving equations or making qualitative evaluations about an object's speed, acceleration and displacement. This chapter can teach you how to do the following:

• Differentiate between scalar and vector qualities
• Solve for variables including distance, speed, velocity and time
• Determine the slope of a line represented graphically
• Interpret graphs used to depict free fall and projectile motion
