1. Bell Ringer 9/8 Speed Displacement How Far How Fast & which Direction
Match the following words to their definition:
Speed
Displacement
Distance
Velocity
How Far
How Fast & which Direction
How Far & which Direction
How Fast
1. C, 2. D B, A.

2. Scalar vs. Vector Scalar Vector
represents a measured quantity (“how much”)
Ex: time, length, mass, distance
Vector
represents both a measured quantity and the direction.
Ex: displacement, velocity

3. Consider the position vs. time graph below for cyclists A and B.
How does the motion of cyclist A (Top) compare to A in the bottom graph? Cyclist B?
What cyclist on the bottom graph has the greater velocity?
Which cyclist has traveled further during the first 5 seconds?
Worksheet 2 – Constant Velocity

4. Instantaneous Speed
Speed at any given instant

5. A woman climbs a hill at a steady pace, then runs down the other side
Distance
Time elapsed

6. Displacement vs. Time Graphs
Velocity:
Speed and Direction
Displacement
Initial Position (start)
Final Position (end)
Direction of Travel
Total Distance Traveled
Displacement
Time

7. Graphing Constant Motion
Constant Velocity: when an object travels the same amount of distance in the same amount of time in the same direction
Distance
Time
Displacement
Time

8. Velocity vs. Time Graphs
Speed of travel
Find the SLOPE:
y2 – y1 or rise
x2 – x run
4 = +1 4

9. Velocity vs. Time Graphs
t (s)
V (m/s)
(+)
(-)
Velocity vs. Time Graphs
Direction of travel
(+) Away from origin
(-) Back Towards origin +2 +1 -1 -2
Not moving toward or away - stopped
