Using a one-dimensional number line to visualize and calculate distance and displacement. Created by Sal Khan.
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.
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.
Example 1. Suppose a dog runs from one end of the street to another end of the street and the street is 80.0 meters across. Moreover, the takes 16.0 seconds to cross reach the end of the street. Now, calculate the speed of the dog? Solution: As we discussed earlier the distance formula can be interchanged to find the speed of the body or object.
Calculate Speed R̅= P 1. A car travels a distance of 540km in 6 hours. Calculate the speed of the car. 2. John is a runner. He runs the 100m sprint in 20.0 s. Calculate the John’s speed. 3. Lauren walks 400 m in 125 s . Calculate Lauren’s average speed. 4. A mouse runs a distance of 2.0 metres in 16 seconds. Calculate the speed of the ...
