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 a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
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!
Using a one-dimensional number line to visualize and calculate distance and displacement. Created by Sal Khan.
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 mouse. 5.
Draw a formula triangle for speed, distance and time. Working clockwise from the top, enter D for distance, T for time and S for speed. Use the formula triangle to work out the correct...
