Velocity–Time Graph from a Position–Time Graph
Goal: Use a position-time (distance-time) graph to draw a velocity-time (speed-time) graph.
1.
Examine the position-time graph below. Complete the following table by calculating the
slope of the tangent at each time indicated.
Time
Calculation of Slope of Tangent
Slope (Velocity or Speed)
2.0 s
4.0 s
6.0 s
8.0 s
12.0 s

2.
Using the times and the speeds from the data chart you just completed in question #1,
draw a speed-time graph. Draw a best fit straight line.
3.
Find the average acceleration of the object for the entire time interval.
4.
Discussion:
a.
What happens to the slopes of the tangents to the distance-time graph as time
progresses?
b.
SNC2D
What does this imply about the speed and acceleration?
