1. If an object moves through equal distances in equal times, then it is moving at a constant _______.   acceleration   displacement   velocity   speed   Hint Half-n-half Clue   2. Acceleration = (change in _______) / (time taken for that change)   force   displacement   speed   velocity   Half-n-half Clue   3. 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   4. Acceleration can be negative.   True   False   5. The line segment BC on the distance vs. time graph given above indicates that the object is moving at a constant speed.   True   False   6. A scalar is a quantity which has both magnitude and direction.   True   False   7. Both speed and velocity have the same units of measurement.   True   False
