Unit Test on Dynamics in 2-Dimensions TODAY! (in marking period 2)

Homework: β Positive Physics unit 11 universal gravitation problems due Thursday at 10pm. Only completion score will count, so keep trying the problems until you get them correct. No late work will be accepted. For additional support on Newton's Law of Gravitation, watch the following video:

### π© 6: M 1/31, π¦ 8: F 1/28 - β©οΈ Pivot circular motion lab (1)

Today, we'll talk very briefly about "uniform circular motion." We'll talk about some variables that we can observe regarding an object traveling in a circle at constant speed. Then, we'll start to work on a lab in β©οΈ Pivot Interactives called "Forces in Circular Motion." I would recommend dividing the work in taking data - first discuss as a group how you will take the data in each part and come to consensus; then each person take their data. The lab is due on Wednesday at at 10pm.

Homework: Finish at least taking data for your part the β©οΈ Pivot Interactives lab. Next time, you will have time to share the data with the others in your group so you can analyze the data together and work on the conclusion. Whole lab is due Wednesday at 10pm.

### π 6: W 2/2, π 8: M 1/31 - β©οΈ Pivot circular motion lab (2)

Today, we'll start class with a geometric derivation of centripetal acceleration. If you missed class or would like to review the derivation from class, you may watch the video. We'll use the rest of class time to share data and make conclusions in the lab.

Homework: Finish the β©οΈ Pivot Interactives lab by Wednesday at 10pm.
