1. If an object moves through equal distances in equal times, then it is moving at a constant _______.   speed   displacement   velocity   acceleration   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   is constantly accelerating at 10 m/s2.   covers a distance of 10 m.   is constantly decelerating at 10 m/s2.   reduces its velocity from 10 m/s to zero.   Half-n-half Clue   3. Which of the following quantities is a scalar?   acceleration   velocity   force   speed   Half-n-half Clue   4. The rate of change of displacement is called   acceleration   velocity   speed   force   Half-n-half Clue   5. 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   6. The line segment BC on the velocity vs. time graph given above indicates that the object is constantly accelerating.   True   False   7. Acceleration = (change in _______) / (time taken for that change)   velocity   force   speed   displacement   Half-n-half Clue
