Measurement and Error

Today we talked about standard units of measurement, why we have significant figures, and the two types of errors.

Notes: Measurement and Error

This weekend please get a lab notebook, preferably with graph paper pages.

Next week we’ll be doing little labs to get familiar with equipment. For homework, think of ways to measure the following that would reduce errors the most:

• Time for a ball to fall a certain distance
• Distance a projectile travels
• Height a ball bounces up to
• Time it takes a toy car to travel 2 meters

Welcome!

Welcome to AP Physics 1 with Ms. Volkening! Today we went over the class policies and procedures, passed out all the paperwork, etc.

Here is the Powerpoint used in class: Day One

You received copies of  a letter for your parent/guardian, a safety contract, and an equation sheet. To save paper, I did not print out the syllabus, but it can be found here: syllabus. Please note that on the parent/guardian letter, the Remind code is @volkening[period], where you put your period number where the brackets are. So if you are in my 4th period, you would use @volkening4 .

You need to bring back the safety contract signed by you and your parent/guardian.

Please also take this survey to help me with preferred names and seats:

The End

Well, it is now the last week of school. Here's what's going on:

Monday, May 20th: Your final lab is due. Come turn it in today even if your class period does not meet.

Monday/Tuesday: We are watching the documentary Tim's Vermeer. There will be an extra credit Plickers quiz at the end.

Wednesday, May 22nd: This is the last day to make up or retake a test and to get regular labs checked. This is the last day I will be available to students. It is a half day with periods 1,3,5 only. We will not be doing anything in class.

Thursday, May 23rd: This is the last day to turn in missing homeworks and extra credits. I will not be here, so just leave everything in the basket. I will not be available to help students as I will be working at graduation all day.

If you will be a senior next year, please fill out the survey at http://bit.ly/UHS2020information  to help me do all the graduation/senior year stuff I have to do. Please also join my Remind by texting @uhs2020fyi to 81010.

Work Time

Weeks of unstructured work time stretch before us. Here are some things you can do:

The Final Lab referenced above is here: Final Lab. It is due May 20th for all classes.

Practice Time

The rest of the week is work time for you to finish all of your homework and to study for the test. You have one last homework, Electricity TIPERs #4, which is due tomorrow. The practice test was also available.

Electricity Test Practice
Key:

Here are some old solutions videos:

#6

#7

#9

#11

#13

#14

#15 (the reading HW I mention in the video wasn't done this year)

Your test is either Monday or Tuesday. You will have a little time to study before it starts.

Compound Circuits

How do you solve a circuit that has both series and parallel components? That was the topic today. We took notes by solving a problem on the board. Here is the result:

Here is a video that I made a couple of years ago solving this problem.

Whatever time we didn't spend on this problem (which is a lot of time) you were working on two worksheets: Concept-Development 35-2 and Compound Circuits Practice. Whatever you didn't finish in class is homework.

Circuit Breakers

Today we briefly talked about circuit breakers (and fuses) - how they work, why we have them, etc. Most of the day was work time, though. I need you all to get your labs done and checked.

Homework is p.644 #37, 38, 40
