Unit 1 Test Review General Physics
1.
Below is a quantitative motion map for a person completing a motion detector lab. The dots indicate a person’s
position each second.
On the coordinate axes to the right, carefully draw and label a
quantitative position-time graph describing the person’s motion.
On the second set of coordinate axes to the right, carefully draw and
label a quantitative velocity-time graph describing the person’s motion.
Describe the motion:
For each of the following graphs in questions 2-3:
a.
Describe, using a clear, complete sentence, how the motion (not the graph shape) of object 2 differs from the
motion of object 1.
b.
Sketch the graph of velocity vs time for object 1 and object 2. (label clearly)
c.
In the space provided, draw motion maps for object 1 and object 2.

4. Using the velocity time graph below, determine the displacement during the following time intervals:
position (m)
Now construct a position-time graph that corresponds to the velocity-time graph in questions #4, above.
Assume a position of zero at t = 0. Be sure to number the position axis scale. Make your graph quantitatively
correct.

5. What is the difference between distance and displacement?
6. How does displacement relate to position?
7. What is the difference between speed and velocity?
8. How does displacement relate to velocity?
9. Convert 4,800 m/s to km/hr.
10. Convert 23 km/hr to m/s.
11. Convert 32,000 mm to m.

12. The object moves in the negative direction at a
steady speed for 10s, then stands still for 10s.
time
13. The object moves in the positive direction at a
steady speed for 10s, reverses direction and
moves back toward the negative direction at the
same speed.
