LET'S INVESTIGATE!
ACTIVITY 1: Measuring Displacement
Objective: Measure and determine displacement of a 10-
centavo coin or a washer
Materials: washer or 10 centavo-coin, centimeter ruler paper
Procedure:
1. Place a washer or a 10-centavo coin on the number line with
the center of the washer or the 10-centavo coin at the position
marked zero.
2. Draw a circle around the inside of the washer or the 10-
centavo coin.
3. Mark the center of this circle with the letter I for the word "initial"
position of the washer.
4. Move the center of the washer 5.0 cm to the right. Label this
circle F for the "final" position of the washer.

Guide Questions:
1. What was the initial position of the washer?
2. What is the final position of the washer?
3. What is the distance traveled by the washer?
4. What is the displacement of the washer?
5. Which of the underlined quantities (final position,
distance traveled, and displacement) are numerically
equal?
