Fortunately, at the same time, it creates more of them. Distance measures the length traveled by an object regardless of start and end-point, whereas displacement is the change in the object's position relative to the starting and ending points. In order to determine distance traveled, you must measure the length of the entire path taken by the object. Direct link to Natalia's post I didn't understand why t, Posted 6 years ago. Practice math and science questions on the Brilliant iOS app. Earth is often used as a reference frame, and we often describe the position of an object as it relates to stationary objects in that reference frame. You might think that this is a Thus, a star at a distance of one parsec would have a parallax of one second, and the distance of an object in parsecs is the reciprocal of its parallax in seconds of arc. If your starting and ending position are the same, like your circular 5K route, then your displacement is 0. Let's set up equations representing the distance the cheetah travels and the distance the gazelle travels.
