Help students learn the difference between distance and displacement by showing examples of motion. As students watch, walk straight across the room and have students estimate the length of your path.
Using a one-dimensional number line to visualize and calculate distance and displacement. Created by Sal Khan.
We will discuss distance, what is the distance formula, its derivation and solved example. We all travel to some area or place on a daily basis and during this travel, we cover some area known as distance.
Distance is the length of the path taken by an object whereas displacement is the simply the distance between where the object started and where it ended up. For example, lets say you drive a car. You drive it 5 miles east and then 3 miles west.
Walk through deriving a general formula for the distance between two points. The distance between the points ( x 1, y 1) and ( x 2, y 2) is given by the following formula: ( x 2 − x 1) 2 + ( y 2 − y 1) 2. In this article, we're going to derive this formula!
