$$\Delta x = x_f - x_i$$

where:

* \(\Delta x\) is the displacement

* \(x_f\) is the final position

* \(x_i\) is the initial position

To use the displacement formula, simply subtract the initial position from the final position. The result will be the displacement.

Here are some examples of how to use the displacement formula:

* If a car moves from 0 meters to 10 meters, its displacement is 10 meters.

* If a ball is thrown up in the air and reaches a height of 10 meters, its displacement is 10 meters.

* If a person walks from one end of a room to the other, his or her displacement is the length of the room.

The displacement formula can be used to solve a variety of problems involving motion. It is a fundamental concept in physics that is essential for understanding how objects move.
