Can’t Tell A velocity graph does not indicate the initial position of the object. B could have had a head start. The speed is indicated by the distance from the X axis on a Velocity graph

Can’t Tell What Does the Intersection Represent? A. They have the Same Position B. Same Velocity C. Same Speed, Opposite DirectionD.

Create a Velocity Graph from a Position Graph Velocity is the Slope of the Position Graph ∆x ∆t (3.0, 3.5) (0.5, 1.0) Slope = 0 Velocity = 0

Create Position Graph from a Velocity Graph Does the Velocity Graph tell you Where to Start? No! Need to be given the initial position

Line Stays at 1 m while Velocity is Zero How Far Do You Go from 3 to 6 seconds?

You end up at 2.5 meter Position at 6 seconds How Far Do You Go from 6 to 9 seconds?

You End Up Back Where You Started What Does the Graph Do Next?

What is Average Speed While Moving? What is the Average Velocity While Moving?

Area “Under” a Velocity Graph is Displacement 0.5 m/s  3 s = 1.5 m -0.5 m/s  3 s = -1.5 m +1.5 m -1.5 m More Correctly, It is the Area Between the line and the X axis Area below X axis is negative displacement

Area “Under” a Velocity Graph is Displacement, even when Velocity Line has a Slope

Area “Under” a Velocity Graph is Displacement, even when the Velocity Line has a non-zero Slope Area = 1/2  4s  0.5 m/s = 1m Area = 1/2  2s  0.5 m/s = 0.5 m Area = 4s .5 m/s = 2 m Increasing Slope Constant Slope Decreasing Slope

Also, Displacement is the Average Velocity times the Time
