This site is a work-in-progress, being created in real-time, as you and your classmates continue working on and submitting your worked-example problem solutions and explanations.
Site navigation: from the menu in the upper righthand corner (upper lefthand corner when viewed on your phone or tablet), you can direct yourself to all of the sub-pages available, each covering a problem that incorporates specific conceptual material from class.
Topics covered thus far include:
2D Motion, Vectors, & Relative Velocity
(Relative velocity of a swimmer across a river current)
(Banked racetrack problem)
Force & Motion Dynamics for Two-Body Systems
(2 masses on a pulley, subject to weight, tension, friction & normal forces)
Angled Tension and Uniform Circular Motion
(Suspended lamp inside a train traveling a circular curved track)
(**2 versions of solution work-through!!)
Gravitational Forces Between Objects
(Newton's Universal Law of Gravitation for spherical bodies)
Conservation of Energy & Centripetal Forces
(Small block sliding down a loop-the-loop track)
Conservation of Energy with Newton's Laws & Kinematics
(Relating the Gravitational Potential Energy and Kinetic Energy of a 2 mass-pulley system using kinematics)Gravitational Torque & Equilibrium
(Balance of forces upon a diving board)
Rotational Motion & Moment of Inertia
(Applying the linear and rotational acceleration relationship for hanging mass on a pulley)
Rotational Motion & Newton's Second Law
(Applying the relationship between rotational acceleration of a pulley and linear acceleration of 2 masses on it)
Rotational Kinetic Energy
(Relating Moment of Inertia, I, and angular velocity, ω, to find rotational KE of 5 ceiling-fan blade system)
Conservation of Momentum in Inelastic Collisions
(Relating post-collision speed and angular momentum to a bullet shot into a suspended block)
(Relating Work and ∆KE to find velocity of deep space probe)
(Change in momentum, and direction of velocity, due to impulse, J, applied -- i.e. due to Force being applied over time)(**2 versions of solution work-through + VIDEO explanation!)
Snapshot & History Graphs
(Snapshot graph -- showing wave displacement as a function of position at a single instant of time; vs. History "time plot" graph -- showing one position as it changes over time)
Simple Harmonic Motion with Spring Oscillator
(Using Hooke’s law relating spring force with displacement from equilibrium, characterizing spring oscillator system in SHM — amplitude, frequency, period, velocity, spring constant k)
(Relating frequency, string length L, number of nodes/antinodes, wavelength, & wave speed)
Sound Intensity & Distance
(Converting decibels to W/m^2 to relate wave intensity with distance away from the source of sound)
(Effect on total amplitude level when 2 waves overlap causing constructive or destructive interference)
We also have a subpage dedicated to our growing set of solutions for Physics 1012 (E&M) topics, which we are working on building up -- this subpage is included at the bottom of the menu, below all of the Physics 1011 topics.
Some of the problems will include two different solution explanations -- one from a group in each section of class. This is included in case one group or another's way of explaining their problem-solving process and reasoning may reasonate with some students better than another, and vice versa.
For the same reason, you will find some of the problems will include either a written-out and/or video-recorded version of the problem solution -- as there are different types of learners amongst your classmates (visual, auditory, tactile).
Check back periodically for updates, and best of luck in preparing for your finals, friends!!!
