B. Distance and Displacement
Read the situation below and do the activity afterwards.
Marie is planning to go to Kaye’s house and ask her about the project in Science.
To reach Kaye’s house, Marie has to walk 150 meters going east. On the way going
east are some establishments- fast food chains, banks and a mall. Then, she will
head to the north at a distance of 230 meters where she can find the church and a
nearby school. Afterwards, she will walk 70 m going west close to River Park to get to
Kaye’s house.
Procedure
1. On a sheet of paper, draw the location of Marie’s house.
2. Guided by the direction below, sketch the path taken by Marie to reach Kaye’s house.
3. Get your ruler and use the scale 10 m = 1 cm.
4. Draw a straight line from Marie’s house to Kaye’s house.
Guide Questions:
1. How far is Kaye’s house from Marie’s place? ______________________
2. How did the given directions help Marie in finding Kaye’s house? ________________
________________________________________________________________________________
3. What do you call the quantity that involves distance and direction?_______________
4. If Marie goes back to her starting position in her house, what will be the total
distance and total displacement? ______________________________________________
5. Can displacement be greater than the distance?_________________________________
6. If you walk from point A to B then to C, what will be your distance and
displacement? Use the figure below to see the path you travelled.
