Distinguish between speed and velocity.
Speed is a measure of how fast an object is moving so it's the distance traveled per unit time. Velocity on the otherhand is the rate at which an object changes a position. Speed is a scalar quantitiy while velocity is a vector quantity. so to measure velocity you also consider the direction of the movement while measuring speed does not. OR The difference between speed and velocity is that velocity is speed with a direction vector associated with it. It's that direction vector that makes them different. Let's back up a bit and review. Speed is displacement (distance traveled) per unit time. Velocity is displacement (distance traveled) per unit time in a given direction. The "directionallity" associated with velocity makes it a vector quantity, while speed is a scalar quantity. Hope this clear it for you.......☺
nice ans
Speed is a scalar (just magnitude) quantity that determines how fast an object is moving. Velocity is a vector (magnitude and direction) quantity that determines the rate at which an object changes its position.
