DAY 41/42 IN AP PHYSICS… WHAT A TIME!
1) Turn in STAIRCLIMBER to me
2) Our plan till Quarter 3
3) Next year plans (does not apply to Julia, Emma, Naz, Twyla, Walter, Isabel, Greg, Caroline, Grace, Miranda, James, and Bryson) but you should think about science as a path. Seriously. Yes, even you.
4) Continue/Start the spring investigation. Note for people that were gone: From the groups today, you might have to schedule a time together (and with me if necessary) to do this.
OUR SCHEDULE: Day 42 (Today): Time in class on spring
investigation and graphs
Day 43 (Mon/Tues): Idea of a ballistic pendulum, You do tough problems in a non-graded format to understand
Day 44 (Wed/Thurs): Review of 2nd Quarter both by me and by you.
Day 45 (Fri/Mon): Start of New Topic: Circular Motion. Idea of circular kinematics.
NEXT YEAR I will come to you and ask sincerely what you
are thinking about for next year and why. This will happen during the period.
If unsure and want my advice, ask! Or see me in the AM!
You have the ability to change it up through the summer in practice.
If you don’t want to continue on in physics, I can accept that. Barely.
If you are a senior, you get to ask me any question you want! I don’t have to answer.
SINCE YOU WERE GONE….YEAH YEAH
If you were gone…gotta do the physical activity of springs with me before the midterm.
A vertical spring is stretched 10cm down from equilibrium and released. Which of these is a correct POSITION graph? Left/Right or Both?
Will the position graph we choose have an effect on the velocity graph we make? NO!
Its why the derivatives of 9x+6, 9x, and 9x-443 are the same.
The ‘vertical shift’ of a sin/cos function does not affect the derivative!
Now draw the Total Mechanical Energy, Kinetic and Spring energy of a ‘dampened’ system where energy is being lost constantly.
