Science Starter! Complete the worksheet “Science Starter!” (on teacher’s desk).
Analyzing “x vs. t” graphs 1. What is the total distance traveled by the object from t= 0s to t = 30 s? 30 m 0 m TOTAL = 50 m 20 m 2. What is the displacement of the object from t= 0s to t = 30 s? t = 0s: object is at 0 m t = 30s: object is at 10 m Δ x = x – xo Δ x = 10 – 0 = + 10 m
Average Speed On the graph shown, determine the average speed from t = 0s to t = 30s.
Average Velocity On the graph shown, determine the average velocity from t = 0s to t = 30s.
Average Velocity (Slope Method) On the graph shown, determine the average velocity from t = 0s to t = 30s. Draw a line connecting the two points. 2. Find the slope of this line: (10 – 0) m = + 0.33 m/s (30 – 0) s
Describe the motion depicted in this particle model. • Create a data chart and graph the motion shown.
Acceleration Rate at which the velocity of an object changes. Vector Symbol: “a” Unit: m/s2
Key Ideas to Remember On a “Position vs. Time” graph: ∙ Linear Line: Constant Velocity - Positive Slope: Moving in (+) Direction (forward) - Negative Slope: Moving in (-) Direction (backward) - Zero Slope: Not Moving (stopped) * Speed: Distance / Time *Velocity: Displacement / Time - Average Velocity: Slope between any two points - Must include either (+) or (-) ∙ Curved Line: Acceleration
