Semester 1 of physics is the study of mechanics, which involves motion and its causes. After reviewing the mathematical skills needed for this study, you will be introduced to vectors, learning how to express quantities including direction and how to deal with vectors in calculations. Next, you will study linear motion and will learn to solve problems involving both uniform and accelerated motion, including the motion of falling objects. In the unit on Newton's Laws of Motion, you will study the causes of motion and will be introduced to motion in two dimensions. Then you will learn about different kinds of forces, from friction to gravitational and centripetal forces. Next, you will be introduced to momentum and energy and will learn how both are conserved. Finally, you will study rotational motion, solving problems involving torque.
Before viewing an episode, download and print the note-taking guides, worksheets, and lab data sheets for that episode, keeping the printed sheets in order by page number. During the lesson, watch and listen for instructions to take notes, pause the video, complete an assignment, and record lab data. See your classroom teacher for specific instructions.
In this unit, students learn about kinetics, which is the study of factors that affect the rate of chemical reactions. Students also investigate collision theory and the five components of kinetic molecular theory in gas.
Georgia Under the Ground explains how Georgia's geography was shaped and molded by the forces of nature. Sweeping scenes show off the geographic variety of the state east to west and north to south and the presence of fossils aids in understanding the formation of the state.
