Today in class we took the fourth reassessment then we went over some housekeeping rules. After this we split up into our stopping distance lab groups and did activity 25 in our MOP books. We learned how to find the area of a graph with constant velocity. To find this you find the area of the rectangle by doing time multiplied by the velocity and then add the area of the triangle by doing half the time by the velocity. Then we graphed the the velocity's and areas. That was what we learned and did in class.

I think we were finding the displacement (area under the velocity curve) for an object with constant acceleration. This led us recognizing why the position of an object experiencing constant acceleration looks like a parabola, and ultimately to the model for position.
