The video tutorial explains the concepts of distance traveled and displacement using a one-dimensional number line. It begins by introducing the number line and the initial position of a lemon. The video then demonstrates how to calculate the total distance traveled by the lemon, emphasizing the importance of absolute values. It further explains displacement as the net change in position, highlighting the significance of direction. The tutorial concludes by comparing distance and displacement, noting that distance considers only magnitude, while displacement accounts for both magnitude and direction.

How is displacement different from distance traveled?

• Displacement considers both magnitude and direction

• Displacement is the same as distance traveled

• Displacement is always positive

• Displacement considers only the magnitude

What is the displacement of the lemon?
