Assume each tick mark represents 1 cm.
Calculate the total displacement from 0 if an object moves 3 cm to the left, then 7 cm to the right, and then 6 cm to the left.
The object moves
cm to the left.
What is the total distance the object travels?
cm
Total displacement = 3 cm (left) - 7 cm (right) + 6 cm (left) = 3 cm - 7 cm + 6 cm = 2 cm to the left
Total distance travelled = 3 cm + 7 cm + 6 cm = 16 cm
