1. A toy plane moves at a constant speed of 5 m/s. It will travel a distance of 125 m in   25 s   625 s   250 s   None of these   Hint Half-n-half Clue   2. 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   3. Both speed and velocity have the same units of measurement.   True   False   4. Speed is defined as   mass / volume   time / distance   distance / time   velocity / time   Half-n-half Clue   5. Acceleration = (change in _______) / (time taken for that change)   speed   displacement   force   velocity   Half-n-half Clue   6. 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   7. If an object moves through equal distances in equal times, then it is moving at a constant _______.   acceleration   displacement   speed   velocity   Half-n-half Clue
