Be prepared to define angular displacement, angular velocity, and angular acceleration.
Be able to solve simple rotational kinematics problems.
Understand how to discuss the moments of inertia of different rigid bodies around a fixed axis, and be able to compute the torque of a rotation causing force. Understand the relationship of torque and moment of inertia in predicting angular acceleration.
Be prepared to apply the concepts of work and energy to rotation.
Understand the Conservation of Angular Momentum, not only for the case of the rigid, rotating body but also for describing the movement of a particle relative to a fixed point in space.
Before getting started with the rest of your assignments, browse Elasticity in the MCAT Primer, perform your basic terms Crossword Puzzle (Solution) and perform an online drill at the Question Server. Remember that the Level 3 terminology is required for the MCAT. Above that level represents a good supplement for MCAT passages.
Browse Fluid Mechanics in the MCAT Primer to get warmed up and then try to do your basic terms Crossword Puzzle (Solution) in one sitting. Perform online drill with the vocabulary at the Question Server. You want to have the basic terminology in hand before watching the videos.
Orient yourself to the basic terminology and conceptual space of Waves before proceeding with the rest of your assignments. Browse the terminology and images within the MCAT Primer, complete the basic terms Crossword Puzzle (Solution) and perform an online drill at the Question Server.
Take a review tour of the Waves resources in the Learning Center.
Understand the fundamental definition of a wave, and be prepared to distinguish transverse and longitudinal waves and assign the different common types of waves to either category.
Be capable of comfortably describing harmonic waves using proper language and comfortably solving basic wave problems involving wavelength, wave speed, period and frequency.
Understand how mechanical waves propagate due to the elastic properties of their particular medium. Be able to explain why mechanical waves in a fluid medium must be longitudinal. Understand how changes in tension and linear density affect the speed of waves on a stretched string.
Be able to describe sound waves both in terms of pressure changes and particle displacements within the medium and describe the roles played by bulk modulus and density ind determining the speed of a sound wave.
Be able to distinguish sound intensity and loudness and solve basic problems involving the decibel scale.
Be prepared to explain the Doppler effect in clear, simple language.
Comprehend how the principle of superposition determines the interference of waves sharing a medium and how beats result from interference. Be able to determine the beat frequency.
Be able to conceptualize how standing waves are created and describe how the boundary conditions of a stretched string (with fixed ends) and an air column (open at one or both ends) play a role in determining the properties of the standing waves that they may contain.
Preview & Review
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!
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?
Read the Coaching Discussions associated with the Main Progression topics of Rotation, Harmonic Motion, Elasticity, Fluid Mechanics and Waves. Start HERE and proceed by clicking 'Next Discussion'.
Relate the special topics in mechanics: Rotation, Harmonic Motion, Elasticity, and Fluid Mechanics to the more fundamental topics: Kinematics, Newton's Laws, Work, Power & Energy, and Momentum & Impulse.
Two or three times this for this module, sit down for one half hour and read from the following works in the category of PHILOSOPHY. With the Santayana, which is a long work, read the first ten pages. Practice reading carefully and slowly. Find the voice in the writing Find the structure of argument. Don't zone out. This is exercise in sustaining attention and concentration. Grip down with your attention and don't let go.
Let's practice being an MCAT test writer. In this exercise, write a 'correct' and an 'incorrect' answer corresponding to questions following a typical verbal reasoning passage. Pretend you are part of a committee making the test, and your job is to write a 'best answer' and a 'second best' (tricky but wrong) answer. We will do this exercise often throughout the course to help you understand the nuances of the Verbal Reasoning questions. Print and complete this exercise. Click Here.
Improve the stamina of your reading attention. Practice sustaining your focus through dense reading material.
Understand the intentions of the writers of Verbal Reasoning questions on the MCAT.
Verbal Reasoning Tip of the Week
Think for a moment after you read a prompt for an author's tone question. Take a moment to think before reading the answer choices. The shades of difference between the answer choices are usually subtle with author's tone questions. Don't let the answers dictate your impression.
