review of rotational mechanics (Thursday retake)
introduction to new material for Simple Harmonic Motion Unit - students made predictions of graphs of F,a,v, and x (all vs. t) for a mass oscillating without friction attached to a spring (all on a horizontal surface) after viewing this video of a mass oscillating on a horizontal spring ... the worksheet is here ... also made predictions for mass oscillating on a vertical spring
discussed what graphs of Uel, K, and Etot for a mass oscillating w/o friction attached to a spring
Students worked on MasteringPhysics assignments

review of rotational mechanics (Thursday retake)
introduction to new material for Simple Harmonic Motion Unit - students made predictions of graphs of F,a,v, and x (all vs. t) for a mass oscillating without friction attached to a spring (oscillating vertically) the worksheet is here
derived/guessed the solution for x(t), v(t), and a(t) for the horizontal mass-spring system
introduced the signature simple harmonic motion equation
discussed an example problem for a horizontal mass-spring system in which the initial conditions where given...found x(t), v(t), a(t), Ule(t), K(t), A, phi, omega, T, and f
discussed now to find x_max, v_max, a_max, and F_max
determined what the total energy of a mass-spring system is at any time
Students worked on MasteringPhysics assignments
Wednesday 3/17/21
review of rotational mechanics (Thursday retake)
discussed the SHM of a simple pendulum using forces and determined the general solution...here is a link that explains the important small angle approximation
discussed the SHM of a simple pendulum using torques
discussed the physical pendulum derivation
discussed the different types of physical pendula (rod, hoop, disk) and found their respective periods
Thursday 3/18/21
livestream will begin after students take retake
Mechanics Exam 5 Retake / students not doing retake worked on UT Quest 19
watched video of comparison of stick pendulum vs. traditional pendulum
discussed torsion pendula
Friday 3/19/21
livestream
students worked on UT Quest 19 online assignment and HRW SHM problems 1-7, 9,10,12,13,16,17
Today's Recording - no recording...students working on assignments
Monday 3/22/21
discussed finding phi and A if one initially knows xi, vi, and omega
discussed vertical mass/spring systems (result is that the period, y(t), etc. is determined exactly the same as if the system were horizontal) ... played around with vertical springs using this simulation
discussed additional numerical examples of a SHO from the blue slides in the notes
discussed solutions to HRW SHM problems 1-5
worked two examples from the notes...the first was a goal-less problem in which we tried to figure out as much as we could possibly figure out
Tuesday 3/23/21
livestream
