Question

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

Answer 1

Net displacement = -3 + 7 - 6 = -2 cm, so the object is 2 cm to the left of 0.

Total distance traveled = 3 + 7 + 6 = 16 cm.
