Purpose:
To use Parallax and triangulation to measure the indirect distance between two points.
Hypothesis:
If a long distance is measured using triangulation then it will produce an accurate measurement.
Materials:
1. Protractor
2. Ruler
3. Tape measure
4. Table or desk
5. Paper
6. Pencil
7. Masking tape
Procedure:
1. Gather all of your materials
2. Clear off your table or desk
3. Place an object at one end of the desk (image A). Using masking tape, label this point C.
4. From the end of the desk opposite the object, estimate the distance to the object. Record your estimate
5. On the end opposite to the object, use masking tape and pencil to make two lines, one at each corner of the table. These lines should be as close as possible to 90 degrees from the table edge. Mark …show more content…
One possible source of error in this experiment is the accurate measurement of the baseline. If an error is made in this measurement, it will create error in the other measurements and calculations.
Identify two more possible sources of error in your investigation.
Angles from A-C and B-C could be calculated incorrectly which would cause the point of C on the scale to be in the wrong spot. Then line C would be a different length and your results would not be accurate.
It is possible to make an error when converting between scale and real diagrams. This could affect your final answer.
6. How carefully did you measure the angles A and B? Explain how the accuracy of these measurements might affect the calculated distance to the object at point C.
I measured the angles very carefully and triple checked that I had the right measurements. If you did not measure the angles correctly then the point C on your scale diagram would be shorter or longer than its actual length. Then, you would get the wrong answer.
7. What are two things you could have changed in the procedure to improve the accuracy of the results? Explain how each of these changes would improve the accuracy of the
