Today in class students took the Forces test. Hope the Force was with them. Have a good weekend. :)

Today in class students reviewed the differences between types of motion graphs plus how to calculate speed and acceleration. Test tomorrow.
Answers to HW: left hand side of the page is straight out of your motion packet, right hand side: 1. Erin's constant speed is 800 m in 4 minutes = 200 m/min. 2. Erin's average speed is 1600 m in 10 minutes = 160 m/min. 3. Erin's average velocity is 160 m/min. east 4. Erin was 800 meters from her house when she stopped to talk. 5. The slope of the line after Erin stopped is 0 m/min. 6. The slope is a way to see the measure of the speed. 7. An object is in motion when its distance from a reference point is changing. 8. Speed in a given direction is velocity. 9. Speed can be calculated if you know the distance an object travels in one unit of time. Today in class students worked in their groups to apply the differences between distance/time graphs and speed/time graphs on the Graphical Analysis of Motion activity.
Answers to HW: have to see the graphs and data tables in class tomorrow. Test Friday. Today in class there was a buzz of activity as students chose groups (including someone they have not worked with before) and began to plan their physics project which will be due Thursday August 17th (day before track out). We also spent time with our classroom groups to continue to dig in and understand motion graphs with a work sheet about understanding and creating graphs. We are focused on two kinds - distance/time and speed or velocity/time.
