1. Analysis of a Distance vs. Time Graph

2. Determining the motion on a D vs. T Graph
Where did the object start?
Which direction did it go?
Where did the object stop?
Is the motion uniform (constant)?
Is the motion non-uniform (changing)?
Can you tell which is faster? (if 2 or more objects are present)

3. d(m) A
Stationary
t(s)

4. Constant Positive Velocity.
d(m) C B
Constant Positive Velocity. D
t(s)

5. Constant Negative Velocity.
d(m) E
t(s)

6. Distance vs. Time Graphs with Non-Uniform Motion
Changing velocity (accelerating)
Changing velocity (decelerating)

7. Slope of a D vs. T Graph Remember, slope = rise/run or
change in “Y” / change in “X”
On a distance vs. time graph:
Rise (Y) = d
Run (X) = t
Slope = d / t  Velocity (m/s)

8. Using slope to predict motion
On a distance vs. time graph
If slope is 0, then velocity is 0.
If slope is positive, velocity is constant in positive direction.
If slope is negative, velocity is constant in the negative direction.
If slope is changing, velocity is changing.(i.e. you are accelerating or decelerating)

9. Same velocity as B. Constant +V V=0 Slower than B or C. d(m) C B A D
t(s)

10. E A
East B
High St. D C
West
