1 SECTION AN OBJECT IN MOTION CHANGES POSITION 10.1 Reading Study Guide
BIG IDEA The motion of an object can be described and predicted. KEY CONCEPT An object in motion changes position. Review Objects can move in different ways.

2 Take Notes Position describes the location of an object.
1. Fill in the outline for position. I. Position describes the location of an object. A. Describing a position 1. A reference point is a location to which you compare other locations. 2. Longitude and latitude help make it easy to compare locations.

3 Describing a Position 2. Fill in the description wheel with information about reference point. Used to describe other locations Latitude and longitude REFERENCE POINT ex: a city A location to which you compare other locations

4 3. Look at the maps in page 314 of your textbook
3. Look at the maps in page 314 of your textbook. Use two different ways to describe the location of Santiago, Chile. Santiago, Chile, is 3000 km southwest of Brasilia. Santiago is at longitude 71°W and latitude 33°S. 4. In question 3, what reference points did you use when describing the location of Santiago, Chile? Brasilia 0° longitude, 0°latitude

5 B. Measuring Distance 5. A car travels from one town to another. What two distances can you measure, and what information does each distance give you? A straight-line path gives you the distance between starting and stopping points. Actual distance traveled gives the distance along the path it traveled.

6 6. What provides evidence that motion has happened?
II. Motion is a change in position. 6. What provides evidence that motion has happened? a change in position Describing Motion 7. Must an object always have the same motion? Give an example to support your answer. No, the motion of an object can change. For example, a person walking might walk faster or stop walking.

7 B. Relative Motion Use the above image to answer questions 8 and 9.
8. If you are seated on the train, who or what would be moving compared with you? Who would be still compared with you? The person outside, the suitcase, and the ground would be moving. The people inside would be still.

8 9. If you are standing outside the train, who or what would be moving compared with you? Who or what would be still? The people in the train and the train would be moving. The ground and the suitcase would be still. 10. Summarize the meaning of relative motion. Relative motion is the concept that the motion an observer sees depends on the observer’s frame of reference. Observers in different reference frames see different motions for the same object.
