1. The rate of change of velocity is called   acceleration   speed   momentum   force   Hint Half-n-half Clue   2. Acceleration = (change in _______) / (time taken for that change)   displacement   velocity   speed   force   Half-n-half Clue   3. The acceleration due to gravity on the Earth's surface is   0.98 m/s2   9.8 m/s2   98 m/s2   980 m/s2   Half-n-half Clue   4. 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   20 m   160 m   100 m   Half-n-half Clue   5. A car moves at an average speed of 50 miles per hour. In 2 hours, it will travel a distance of   5 miles   25 miles   100 miles   None of these   Half-n-half Clue   6. If an object moves through equal distances in equal times, then it is moving at a constant _______.   speed   acceleration   velocity   displacement   Half-n-half Clue   7. Both speed and velocity have the same units of measurement.   True   False
