This document provides a review for a physical science exam covering motion, speed, and acceleration. It instructs students to bring a calculator and ruler to the exam and study vocabulary from sections on relative motion, vectors, scalars, speed, distance, time, velocity, and acceleration. It provides example problems for students to practice calculating speed, distance, time, velocity, and acceleration using equations like speed=distance/time and acceleration=change in velocity/time. Students are asked to analyze distance-time and velocity-time graphs to determine speed and acceleration over different time intervals and describe object motion.

1. Physical Science Review for Period Exam I
Bring your calculator and your ruler to use during the exam.

Section 1.1C Motion
Relative Motion
Give an example of relative motion and mention the motion that is
taking place depending on your frame of reference.
Vector and Scalar
Draw examples of vector quantities and scalar quantities.
Draw a vector for each quantity, give the scale you used.
