Is the distance from where you start to where you finish. . Δ. d=. d. f. -d. i. Velocity:. How fast and in what direction (vector quantity). V = ∆d/t. Speed: . How fast (scalar quantity). Velocity and acceleration Measuring an objects motion speed Speed is calculated by dividing distance by time S = d/t 5.0 km/h 2.5 m/s 45 mph velocity Velocity is the same as speed, but you tell the direction of motion in the answer. Acceleration is a measure of . the change in velocity per unit of time. When the velocity of an object is changing, it is . accelerating. Negative acceleration: . slowing down. Positive acceleration: . What is acceleration?. If you’re traveling in a car at a constant speed of 50 mph, are you accelerating?. No, you’re not. . Acceleration is the rate of change of velocity. . Acceleration. In order for acceleration to occur, velocity MUST be . Defination. In non-uniform motion,the velocity of a body changes with time . For example, when a train leaves or approaches the platform its velocity changes with time. The change in velocity of an object with time is given by a physical quantity known as acceleration. .
