For one dimensional motion constant velocity is given by this formula. _____ Equation_____ b What is the relationship between the slope for the position vs time graph and the velocity. Tangent lines are shown for two points in Figure 213.
This lesson addresses the HSF-IFC7 and HSS-IDC7 standards because it asks students to use mathematical reasoning to interpret the meaning of one graph to generate average velocity and average speed for an object.
The Importance of Slope. That was pretty clever how you neatly and cleanly cut off the part of the photo that shows the formula were supposed to use. On a position vs time graph the average velocity is the slope of the secant line joining the position at the beginning and end of Delta t. M Y Ernie Y Bert X Ernie X Bert Slope Formula Tips and Tricks The slope formula can give a positive or negative number as a result.
