Tomorrow we will have a quiz on constant velocity motion. You should be familiar with interpreting a position vs. time graph, describing the motion that is being shown in a graph, making a velocity vs. time graph from a position vs. time graph, displacement, distance, average speed, average velocity, and solving constant velocity problems.

Today we gathered position vs. time data for a marble rolling down an incline. We will use our data to create mathematical models for accelerated motion. When you graph your paper, put the horizontal axis (time) on the long edge of your page, and the vertical axis (position) on the short edge. Make the graph as large as possible.
Today we solve speed and velocity problems in groups on large white boards. The problems were on p. 53 #1-9. We will go over the challenging problems together tomorrow.
Today we practiced using x vs. t and v vs. t graphs. We described the motion that was depicted in the graph, and practiced going form one graph to another.
Today we discussed our graphs from the buggy lab. We discussed the significance of the slope of the position time graph as well as the y-intercept, we created a velocity vs. time graph for our buggies, and we derived a general equation for the motion of any object moving at constant velocity. Tomorrow we will learn some new vocabulary: distance, displacement, speed, velocity. NOTE: You need to use your svsd google account to see the class notes linked above.
Today we began to talk about motion in a straight line. You gathered position vs time data for two different buggies. Please graph your data (position on the y-axis, time on the x-axis) for both buggies. You can graph both buggies on the same coordinate axes, but you should use different colors so you can easily tell which line corresponds to which buggy.
On Tuesday we went over the class policies and syllabus. You each received a copy of the class syllabus. Please read through the syllabus with your parent/guardian. Once you have read it, please complete this form to indicate that you have read and understood the class policies. This is due by Friday 9/8.
