Example Question #1 : Mechanics Principles

A car drives miles east and miles north. What is the total displacement of the car?

Possible Answers:

Correct answer:


The car has covered a total distance of miles, however, displacement and distance are not the same thing. Distance is simply the measure of how far the car have moved, regardless of direction. Displacement is a vector quantity, and takes direction into account. Displacement measures the total distance only between the car's starting point and ending point.

To solve this question, it is best to draw a sketch. The resulting sketch will be a right triangle with the hypotenuse equal to the displacement. The Pythagorean Theorem can be used to solve the problem.
