Science Starter!
Complete the worksheet “Science Starter!” (on teacher’s desk).
Analyzing “x vs. t” graphs1. What is the total distance traveled by the object from t= 0s to t = 30 s?
(A) 30 m(B) 0 m TOTAL = 50 m(C) 20 m
2. What is the displacement of the object from t= 0s to t = 30 s?
t = 0s: object is at 0 mt = 30s: object is at 10 mΔ x = x – xo
Δ x = 10 – 0 = + 10 m
Average SpeedOn the graph shown, determine the average speed from t = 0s to t = 30s.

Average Velocity (Slope Method)On the graph shown, determine the average velocity from t = 0s to t = 30s.
2. Find the slope of this line:
(10 – 0) m = + 0.33 m/s (30 – 0) s
1. Draw a line connecting the two points.
