is Vectors are represented by arrows. The length of the arrows indicate the magnitude of the vector, and the arrowhead points to the direction of the vector. In our example, the displacement is drawn at a scale: 1 cm = 10 cm, directed to the east. ne EXERCISES 1. A group of mountain climbers walked 10 km north from their camp, then walked 20 km more to the east. a. What was the total distance walked by the mountain climbers? b. Determine the total displacement from the starting point. 2. I walked 1 km N, 2 km E, 3 km S, and then 4 km W. What is the total distance I traveled? What is my total displacement? The speed of an object is a measure of how fast it moves. If the object is moving from on position to another in a measured time, its average speed v is obtained by dividing the distan traveled by the time taken to cover the distance. In mathematical form, Speed
