October 8
Swbat make test corrections on separate paper and resubmit. Graph linear motion on position, velocity and acceleration time graphs. Swbat to determine the change in position, velocity from the other graphs.

Use the picket fence lab to determine the acceleration due to gravity on earth. Determine if acceleration is the same if the object is thrown vs. dropped.

Complete graphing worksheet for next class. (I need to copy these and post them here)

October 10
Activity: You will be given 6 washers and a long piece of string. You are to tie the washers onto the string such that the clap the washers make into a metal pan placed on the floor is steady (equal time).

Create a position time, velocity time and acceleration time graph for this event. (time on the x-axis) Remember acceleration is negative!

Picket fence demo.

Write a brief summary of what you learned by this activity.

Graphs and and summary due next class.

October 15
Complete Free Fall activity. Complete Standard Test Prep at the end of Ch 2 linear motion.

October 17
PSAT Testing no class

October 19
Review Std Test Prep Ch 2. Objective: Define and differentiate vector and scalar quantities. Be able to graphically add vectors using the head to tail method. Understand the limits and the benefits of applying vector analysis.

Introduction to vectors Ch 3. Intro to vectors Video see section L3.1 Graphically find the components of 10 m East 20 m North 50m @30 NE 60 m @60 NW 80 m @45 SW 100 m @ 25 SE

Graphically Add 1) 10 m E ;20m S ; 45 m @30 NE 2) 100m S; 250 m N; 300 m@60 SW 3) 10m W; 30 m S; 50 m@45 NE 4) 400 m @30NE ; 500m @60 SW ; 700m @45 SE;

October 23
Review graphical method of adding vectors. Objective: Define trigonometry functions to define ratios of sides of a right triangle. Use these functions to find the components of vectors. Add vectors mathematically using component methods.

Why: Vectors are useful tools to evaluate most problems. Computer analysis, games etc all use vectors to make the motions look real and engineers use vectors to design buildings and analyze parts.

Watch this video on trig functions (L3.0 Trig on left tab) to review. The homework problems are at the end of the video.

How: Apply mathematical methods to the same graphical problems above. Compare the mathematical results to graphical, Are they within 5-10 percent error?

October 25
Continue practice of adding vectors. P 85 #1-3, P 89 #1-44, P 92 #1-4 Be prepared for a quiz next class on adding vectors both graphically and mathematically.

October 29
Quiz on adding vectors both graphically and mathematically.(formative?)

Introduction to Projectile motion. How do vectors describe the independent nature of two dimensional motion. Describe the independent motion of an object under two independent motions in different directions without acceleration.

Read and take notes on Ch 3 p95-107.

October 31
HOW: Draw a projectile by first drawing a projectile assuming no gravity. and then investigating the effects of gravity.

November 2
Complete projectile plot and analysis questions. Due next Class November 7.
