For example, the nearest star, Proxima Centauri, which is part of the Alpha Centauri triple-star system, has a parallax of 0.769 second of arc, and, hence, its distance from the Sun and Earth is 1.30 parsec. Distance is how much ground is covered by an object, regardless of its starting or ending position. Distance traveled is not a vector. This means that, unlike force and velocity, it has no direction, only a magnitude. While every effort has been made to follow citation style rules, there may be some discrepancies. And to get to the next galaxy? If your starting and ending position are the same, like your circular 5K route, then your displacement is 0. For example, a problem might say: "Find the distance a car has traveled in fifteen minutes if it travels at a constant speed of \(75 \text {km/hr}\)." Distance is the total movement of an object without any regard to direction. In October 1997, this special supercar achieved a speed of up to 1227.985 We can define distance as to how much ground an object has covered despite its starting or ending point. 04 Over 7 million people in the world have careers in science.
