Today we worked in groups on some of the book problems dealing with constant velocity motion. Please complete the WebAssign assignment if you have not already done so.

Today we looked at the position time graphs that you created on Friday. We talked about the meaning of the slope of the position-time graph, the meaning of the y-intercept (position graph), and how we can go from a position time graph to a velocity time graph, and vice versa. Then we derived a general kinematics equation for constant velocity motion, and began solving problems. Homework is on WebAssign (Constant Velocity Problems) and is due on Wednesday.
On Friday we collected position and time data for a fast and a slow motorized buggy. You should graph your data for both buggies on the same axes (position on the y-axis, and time on the x-axis). Draw a best fit line and calculate the slope of each line.
Today we finished discussing the difference between distance and displacement, and speed and velocity. Now you should be able to complete the first WebAssign assignment. Tomorrow we will work with the motorized buggies to gather data to make a position vs. time graph of their motion.
Today we began setting the stage for our study of kinematics by defining position, displacement, distance, speed, and velocity. We also learned how to read and use motion diagrams to model different types of motion. We will finish the notes tomorrow. Homework is posted on webassign (Describing Motion - 9problems) with a due date of Friday. We still need to cover a few definitions before you can do the homework.
Today we looked at the data from the pendulum lab and tried to determine the mathematical relationship between the variables. We discussed the meaning of the y-intercept, and then talked about how to modify the data to get a linear graph which we could then use to write an equation. Homework is a worksheet to practice finding the mathematical relationship between variables using linearization (if needed). The worksheet has 4 data sets on it. You do not need to graph all 4. Try to write the mathematical equation for one data set. You can do more if you need more practice. You can use EXCEL or your graphing calculator to help you graph. You do not need to graph everything by hand.
Today you received the instructions for creating a WebAssign account at webassign.net . If you lost your sheet, you can download a new copy here: https://webassign.net/manual/Student_Quick_Start_Guide_SE.pdf
The class code fo AP Physics 1 is mountsi.wa 4278 7614 There is optional additional content available for our textbook - you are not required to purchase it for class. You are only required to purchase access to online homework for $10.50. If the cost of access is a burden to your family, please use this link: https://goo.gl/forms/KbaGbnPNUKHgvdZC2 to send a request to the counselling center and they will help find a way to support you, no questions asked. Friday we finished gathering data for the pendulum lab. If you have not already done so, please graph your data over the weekend and be ready to talk about it on Tuesday. Today you designed an experiment and gathered data to determine the relationship between the length and period of a simple pendulum. The requirements for the writeup and graph are on google drive in the week 1 folder. Tomorrow we will talk about the best fit curve for your data, and determine the equation of the best fit curve.
