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 interactive virtual learning journey, students will explore the peanut industry, history and origins of the peanut plant, various ways peanuts are used, and how peanuts impact our economy...
Here in Georgia, blueberries are starting to give the peach more than just a little competition. During our visit with the folks at Cogdell Berry Farm, we start things off by listing the best ways to eat blueberries and we finish with a few surprises. For example, Cogdell Berry Farm uses laser beams to help sort their blueberries. And this is the type of technology that’s made Georgia one of the most productive blueberry states in the country. We’re only sorry you can’t taste this video. These blueberries are delicious!
