Circuits conceptual check ins:What is polarization? How do charges move in a conductor when a charged object is brought near?How do charges move in a non-conductor when a charged object is brought near?What are the physical analogies for current, resistance and voltage?When is current the same in two components of a circuit?When is voltage the same in two components of a circuit?What does parallel and series mean?What happens with resistors added in parallel?What happens with resistors added in series?What does coulomb’s law tell us? When is it used?What is power, conceptually?Batteries provide a constant source of: _________How does the resistance of a resistor depend on its length and area? How does resistance change as you change each of those?SHM conceptual check ins:The velocity of a mass oscillating on a spring is maximum when: the mass is at maximum displacement OR the mass is at equilibrium position OR neitherThe potential energy of a mass oscillating on a spring is maximum when: the mass is at maximum displacement OR the mass is at equilibrium position OR neitherHow are period and frequency related?Why doesn’t the period of oscillation depend on the amplitude?Why does increasing the mass on an oscillator increase the time it takes to oscillate?What is a natural frequency?What is resonance?Waves conceptual check ins:What’s the one equation you MUST remember for waves?How are wavelength and amplitude measured? (where in a picture)What happens when two wave pulses interact with one another?What happens when a wave reaches a boundary of the different types?What is the Doppler effect?Why does the Doppler effect happen?What is required for a standing wave to happen?What are the shapes of standing waves for the different boundary conditions? What are the wavelengths for those cases?How does resonance work with standing waves?Rotation conceptual check ins:What are the rotational analogies to: position, velocity, acceleration, mass, force, momentum, energy?What has to be true for an object to be in rotational equilibrium?How do you use the torque equation? What do the variables represent?When working with an object that isn’t just a point, where do we say the force of gravity is acting?What sorts of problems require the use of more than one pivot point in their analysis? What determines the moment of inertia of an object?When an object rolls without slipping, what does that let us know?For an object that rolls down an incline, what is true about the energy?How do pulleys with inertia impact the forces in pulley problems?How is angular momentum similar to and different from linear momentum?EnergyWhen is energy conserved?What types of problems/situations do not have energy conserved?What are the main types of energy we have worked with?How is work connected to energy? When is work positive/negative?How do you maximize the work done by a force? (When is a force no good for doing work?)How can you find work from a graph? What types of graph could let you find work?What is mechanical power and how is it connected to work?What does “mechanical energy” mean?Forces and frictionWhen drawing a free body diagram, what are some rules to follow? (What shouldn’t you include? What aspects should you be extra careful with?)When is tension different in different parts of a pulley problem?What is the behavior of the two different types of friction? When does friction match your force?What factors influence the force of friction? (there are two different aspects of this)What determines “apparent weight”? When can your weight seem different from your actual weight?Circular motionWhat is wrong with the idea of there being an extra centripetal force when circular motion is happening?What are the concepts at play when an object swinging in a vertical circle “barely makes it” across the top?What are the two expressions you need to use for acceleration in circular motion problems?MomentumWhen is momentum conserved? When is it not conserved?What is impulse? What graphs can be used to calculate impulse?How does the center of mass move when you have multiple objects colliding?Explain the difference between elastic and inelastic collisions.What is the difference between KE and momentum? How does the vector aspect make momentum work differently from KE? ................
