ELI5: Explain Like I'm 5

Displacement (vector)

Displacement is like moving from one place to another, but we want to know how far and in which direction we moved. Imagine you are playing with your toy car and you move it around your room. You can say that you moved your car from your bed to your toy box. This means that your toy car changed its position and moved from one place to another.

Now, let's say you have a big arrow that shows how far and in which direction you moved the toy car. This arrow is called displacement. If you move the toy car five steps to the left, the displacement arrow would show that you moved five steps to the left.

You can think of displacement as a map that tells us exactly how far and in what direction you moved. Displacement is also called a vector because it has both a direction and a magnitude (a quantity with a size or amount). The direction is where you are going, and the magnitude is how much you moved.

So the next time you move something from one place to another, you can use displacement to describe exactly how far and in what direction you moved it.
