Distance and displacement in one dimension | One-dimensional motion | AP Physics 1 | Khan Academy

Starting from a pillar, you run a distance 140m east (the + x-direction), then turn around.&nbsp;(a) How far west would you have to walk so that your total distance traveled is 300m?(b)What is the magnitude and direction of your total displacement?

Displacement in 1D

Displacement verses Distance
