What Is The Word For Speed And Direction? Velocity is quickness of motion or action. A synonym is celerity; a simpler word is speed. In physics, velocity specifically refers to the measurement of the rate and direction of change in position of an object. It is a vector quantity that specifies both the speed of
How Do We Measure Velocity? Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the
What Are Two Things You Need To Know To Describe The Velocity Of An Object? Velocity is a physical vector quantity; both magnitude and direction are needed to define it. Which 2 things must you know to find the velocity of an object? When you know both the speed and direction of an object’s motion,
