1. Bell Work: Car Lab
The car’s speed was ( constant / changing ) throughout the race.
As the distance increased, the time ( increased / decreased ).
So for the constant speed car, the distance and time are ( directly / inversely ) related.
A graph of 2 things directly related will have a ( positive / negative ) slope.

2. Linear Motion (Ch2)

3. Time How long does it take? Scalar (no direction) t = time
units: seconds (s), hour (h), minutes (min)

4. Distance How far? Scalar d or x = distance
units: meters(m), centimeters(cm), kilometers(km)

5. Displacement How far? Vector (has direction) d or x = displacement
Ex: 4 cm north
2.07 km left
0.043 m up

6. Speed How fast? Scalar v = speed Δv = change in speed
units: meters per second (m/s), centimeters per second (cm/s), kilometers per hour (km/h)

7. Velocity Vector v = velocity Δv = change in velocity Ex: 20 m/s north
1.7 cm/s right

8. Acceleration Vector a = acceleration units:
meters per second squared (m/s2 or m/s/s)

9. Position Direction Where you are located
Which way you are moving; the course you take to reach your destination

10. Which is most similar to speed?
Acceleration Displacement Time Distance Velocity

11. Which is most similar to distance?

16. Which are displayed in a car?

17. Which is a change in position?
Acceleration Displacement Time Speed Distance Velocity

18. Which is a change in velocity?
Acceleration Displacement Time Speed Distance Velocity

19. Which is speed plus direction?
Acceleration Displacement Time Speed Distance Velocity
