 ## what is motion in physics? The concept of displacement and distance

Toward bright spark; We say that a body is in motion when the position of a body changes with respect to an origin. For example, a car is going from city (A) to city (B) through a highway, or the moon orbiting Earth. The simplest type of motion is the motion along a straght line (one-dimensional motion).

## Position vector:

Position vector is a vector starting at origin, where the position (x) is equal to zero, ending at the current body’s position. In the above vector, is the unit vector and (x) is the body’s position.

## Displacement and distance:

Displacement is a vector witch connects the start of a movement to its end and distance is the length of the motion path. Now that you are familiar with the concepts of motion ,displacement and distance, you can install Toward bright spark app, review them as a video tutorial and learn their key points.
