DAY 17
I'm out today - please follow the time schedule as listed here.
Warm-Up:
1. (5min) Rearrange the following equation to solve for the variable in bold
a. accel: df = di +vit + 1/2at2
b. initial velocity: vf = vi + at
c. time: df = di +vit + 1/2at2
2. (5min) Check and correct your answers here ---> LINK
3. Warm up check next class
8:40AM CLASSWORK:
0. Refresh the page
1. Kinematics Review (30min)
a. Practice Kinematics Exam
b. review of answers ---> LINK
2. Acceleration of a Falling Marble Lab
The handout was give to you last week - if you lost it it's here ---> LINK
HOMEWORK:
1. Pit-falls of Free Fall
Take Day 17 Notes: List the pit-falls (if you missed some, the notes are HERE)
Answer the edpuzzle questions
LINK to video
2. Complete Kinematics Test #1 Study Guide. Show your work. Post work/answers to GC.
3. Bring Marble Lab to class with data collection complete. Share video with me at j.alexander@tch.birminghamcharter.com
09/23/16
WARM-UP:
1. Look up the definition of acceleration, and copy it into your notes.
2. What is the symbol for acceleration?
3. Can acceleration be negative, or only positive?
CLASSWORK:
1. CH2 Exam
2 parts - written and problem solving
2. CH3 Accelerated Motion
When you're finished, you'll begin an introduction to the concept of acceleration.
a. Watch https://edpuzzle.com/media/5782b73e27ed9aaf1338582f
Answer the questions, and also take notes on what Mr. P shows you with his Prius, and what he shows on the whiteboard. You can watch this on the computer or phone using headphones, or using closed captions (the CC button)
b. Read CH 3 pg 57-60. Review Example Problem 1 on pg 60
Individually: while reading, I want you to write down ten facts, similarities, or differences you've found. Facts could include symbols, equations, definitions, descriptions, etc.
Whole Class: after reading, chose your best piece of information, and share with with the class by posting it here --> LINK. This is first come, first serve. You'll need to read the other posts to make sure you don't repeat what anyone else posted...
c. Solve pg 61 1-3
Homework
If you didn't complete the classwork, I'll be checking it Tuesday for credit. Finish it by them. Remember, Labs are due tonight by midnight.

WARM-UP
1. Look up the definition of "kinematics" online. Click on at least two websites. Write a solid 1-2 sentence definition of the term.
2. What do you think the prefix "kine" means? kinect ,
Kinesiology, kinematics
3. Recall Δx. Write the equation that relates change in position to time and velocity
Any homework questions?
GOALS: SWBAT...
- demonstrate a v-t graph through live motion
- interpret velocity and acceleration via a v-t graph
CLASSWORK
1. NOTES (copy/summarize these)
Kinematics: What is it?
Kinematics describes the motion of objects. Kinematics equations are used to represent/describe/predict the motion of objects.
Kinematics Equations:
Position: Δx=vΔt can we solve this for xf (final)? Try it :-)
Final Position:
Acceleration: a=Δv/Δt can we solve this for vf (final)? Try it :-)
Final Velocity:
Often we're trying to figure out velocity or acceleration at the end of a time period - that's where these final position and final velocity equations come in handy.
2. Those equations will come in handy right now :-)
Individually, use the GUESS method and the kinematics equations to solve problems 19-21 on page 65. Consult with your groupmates if you get stuck or are unsure.
3. Review #2 as a class
4. Walking Through Graphs
Mr A will be assigning graphs from those pictured here. Each team will randomly be given a graph and asked to depict its motion by walking. The rest of the class will evaluate their effectiveness.
5. Position and Acceleration Quiz Thursday
HW due Thursday. More Accel stuff Thurs... FUN! :-)
- pg 64. #13 & 15
- pg 65. #18
- pg 67. #22 & 23
Bonus Points if you know this song
Warm-Up
Q from video (maybe this is follow up) and figure from pg 58 & 59
Follow up on Video and HW problem
Introduce concept of acceleration
Direct Measurement Videos
Maybe do the Mini Lab from page 58 (maybe not thoe)
Is this acceleration? Why or Why Not?
Sample Problem
Prepare for Walking Thru Graphs
HW?
