1. Acceleration = (change in _______) / (time taken for that change)   velocity   speed   force   displacement   Hint Half-n-half Clue   2. Consider the graph of velocity (in m/s) vs. time (in s) given above. During the last 2 seconds, the object   covers a distance of 10 m.   reduces its velocity from 10 m/s to zero.   is constantly decelerating at 10 m/s2.   is constantly accelerating at 10 m/s2.   Half-n-half Clue   3. The rate of change of velocity is called   force   acceleration   speed   momentum   Half-n-half Clue   4. The rate of change of displacement is called   speed   acceleration   force   velocity   Half-n-half Clue   5. Consider the graph of velocity (in m/s) vs. time (in s) given above. In the first 8 seconds, the object has traveled a distance of   110 m   160 m   20 m   100 m   Half-n-half Clue   6. The line segment BC on the velocity vs. time graph given above indicates that the object is constantly accelerating.   True   False   7. A bus covers a distance of 120 miles in 4 hours. Its average speed in miles per hour is   3   30   480   None of these   Half-n-half Clue
