物理学 101 - 古典力学 (6 件中 1 件) [科学]

This class is designed to provide an introduction to the basics of classical mechanics: the study of motion, and forces.  Many topics will be covered over this 5 week class that will give the student a basic understanding of the physics behind motion and forces they see in their everyday life.  Students will have the opportunity to practice what they learn each week.  

Week 1: Kinematics 
-> Video: Scalars vs. Vectors and Units of Measure
-> Video: Kinematics: About Motion
-> Fill in the blank note sheets for each video
-> Practice problems: difference between scalar and vector quantities; difference between speed, velocity and acceleration; general understanding of motion

Week 2: Newton's Laws of Motion
-> Video: Newton's 3 Laws of Motion
-> Fill in the blank note sheets for the video
-> Practice problems: Describe each of the 3 laws of motion, application of each law of motion

Week 3: Forces in everyday life: Gravity, Friction, & Centripetal Force
-> Video: Friction
-> Video: Gravity
-> Video: Centripetal Force
-> Fill in the blank note sheets for each video
-> Practice problems: Simple problems on each of the three forces: gravity, friction, and centripetal force

Week 4: Simple Machines
-> Video: The Simple Machines (Inclined Plane, Wedge, Screw, Lever, Pulley, and Wheel & Axel)
-> Fill in the blank note sheets for the video
-> Practice problems: Applications of simple machines

Week 5: Why do boats float, and planes fly? Special applications of unique forces
-> Video: Why do boats float (buoyancy force)
-> Video: How do planes fly (lift and drag forces)
-> Fill in the blank note sheets for each video
-> Practice problems: Applications of these unique forces

This is a flexible schedule course, meaning that there are no live meetings. Each week, new videos, notes pages, and practice problems will be posted to the classroom. The completed practice problems will be uploaded to the classroom (either scanned or a picture taken) for feedback from the teacher.   There will be a discussion thread where students can ask for help from the class and the teacher.  To get the most out of this course, the teacher will provide notes pages with blanks for the students to fill in as they watch the videos.  Students are expected to complete the practice problems each week as the material builds upon itself weekly.
 
The teacher is always be available via message (either in the classroom discussion or private message) and will typically reply within 12 hours, but never more than 24 hours unless extenuating circumstances.
