AP Both Unit 4 - Energy, Work, Power
Monday 11/2/20
eLearning
students should carefully study solutions to examples of non-uniform circular motion on pp 67-70 of notes. Students are responsible for this information.
Complete the Pivot Interactive: Spring Force Scaffolded
What you need to have completed by 11:59pm: UT Quest; Pivot Interactive. You may discuss the Pivot in the Google Classroom thread for today's assignment. Have a great day.
Wednesday 11/4/20
eLearning
we will begin today's class w/ a video of me doing an experiment and then work through some notes on calculating energy.
discussed the definition of work and how it can change energy
discussed the dot product and did some example dot product calculations
students need to complete the APCB8 2021 (Mastering) assignment by 11:59pm tonight.
Thursday 11/5/20
eLearning
discuss more of problems from Unit 3 Notes
discussed the dot product in more detail
students work on online homework due this evening
Friday 11/6/20
eLearning
discuss more of problems from Unit 3 Notes
discussed the work/kinetic energy relationship with multiple examples
explored new Google Meet features (breakout rooms, Q and A, and Polls)
introduced students to their assignment for this weekend (M problems and B problems)
Monday 11/9/20
livestream
discussed solutions to (M problems and B problems)
discussed a plethora of work/kinetic energy examples
discussed calculating work done by a force NOT proportional to stretch/compression (requires integral to find area of F(x) vs. x graph
Tuesday 11/10/20
livestream
continued discussing a plethora of work/kinetic energy examples (some examples in notes are worked but not discussed)
discussed calculating work done by a force NOT proportional to stretch/compression (requires integral to find area of F(x) vs. x graph
discussed using the integral form of W = int (F(x)dx

whirligig prelab discussion
whirligig lab
discussed several problems using conservation of energy
Thursday 11/12/20
livestream
discussed several problems using conservation of energy
demonstrated that W=delta K produces same results as conservation of energy
introduced universal gravitational force law: Fg = (GMm) / r^2
showed that GMe/re^2 was equivalent to g or 9.8 m/s^2
derived Ug(r) = - GMm/r
introduced the equation of greatness
used the equation of greatness to solve several problems
introduced U vs. x graphs (force is negative slope)
worked with several situations in which U(x) vs. x was given
Friday 11/13/20
livestream
re-derived Ug(r) = - GMm/r
introduced U vs. x graphs (force is negative slope)
worked with several situations in which U(x) vs. x was given
students worked M11 (only gave them 10 minutes)
Monday 11/16/20
livestream
discussed several problems in which the equation of greatness could be implemented (one was given a position-dependent force and the other was given a potential energy function)
discussed a couple of familiar situations (Atwood's machine and a mass sliding down a frictionless ramp) in which forces or energy could be used to analyze
discussed several MIT problems involving energy
reviewed main topics for Wednesday's Unit 3 exam
Tuesday 11/17/20
livestream
discussed definition of power
