Preview & Review

Assignments

Browse your Examkrackers Physics book from beginning to end. Study the table of contents. Read the bold headings and the formulas. Look at the figures. Get a bird's eye view on Physics. (You can do this assignment just as well using other learning materials, such as those from Berkeley, Kaplan or TPR). By the end of this course you will have a strong imprint of what every page looks like in this book. You want to get as many cycles through it as you can. As in the first module of the course, spend some time practicing with the WikiPremed outline of physics HERE to make sure you can reproduce the outline in full if given a blank sheet of paper. Sit down and try to write it out until you can do it!

Activate

Goals

Keep working on your ability to outline physics. Make sure you can outline Physics in a clear, conversational manner: Mechanics, Waves, Thermodynamics, Electricity & Magnetism, Light & Optics, Modern Physics, Nuclear Physics and then going further to the subtopic level within each of these topics. Within Mechanics, for example, you have Kinematics, Newton's Laws, Work & Energy, Momentum & Impulse, Rotation, Harmonic Motion, Elasticity, & Fluid Mechanics.

Hold yourself accountable for having a mental picture of the field of reference for each subtopic. Try to think of the simplest situation describing the phenomena. What is the simple model system for each subtopic?
