1. What Information Can We Take from Graphs? Finding displacement from a v-t graph AND Finding acceleration from a d-t graph

2. IN CLASS PRACTICE PROBLEMS

3. ANSWER KEY

7. NOTES This handout is on my Connect site under “Physics – Handouts.” It’s called “Acceleration from a d-t graph”

9. 1.Graph the data on a d-t graph 2.Smoothly sketch a best-fit curve 3.Find 4 points on the curve (evenly spaced apart) and calculate the instantaneous velocity (show tangent line and all work) 4.Fill in this table 5.Sketch a v inst -t graph 6.Calculate the slope (with units!) 7.Fill in the blank: The slope tells us the ________ of the plane.
