The rate of change of velocity is called   speed   force   acceleration   momentum   Half-n-half Clue   3. Consider the graph of distance (in m) vs. time (in s) given above. After 8 seconds, the object has traveled a distance of   110 m   20 m   100 m   160 m   Half-n-half Clue   4. Consider the graph of distance (in m) vs. time (in s) given above. The object's speed during the first 5 seconds is   4 m/s   5 m/s   20 m/s   100 m/s   Half-n-half Clue   5. Acceleration = (change in _______) / (time taken for that change)   speed   displacement   force   velocity   Half-n-half Clue   6. Both speed and velocity have the same units of measurement.   True   False   7. Which of the following quantities is a scalar?   acceleration   velocity   speed   force   Half-n-half Clue
