Acceleration is a vector because it has a magnitude and a direction (Accelerating at a rate of 5 Miles Per Hour North). Speed is a scalar because it only has a magnitude (35 Miles Per Hour) . Velocity is the derivative of the acceleration and is also a vector (35 miles per hour North). Adam Â· 5 years ago. Thumbs up.
Acceleration, in physics, is the rate of change of velocity of an object. An object's acceleration is the net result of any and all forces acting on the object, as described by Newton's Second Law.The SI unit for acceleration is metre per second squared (m/s 2). Accelerations are vector quantities (they have magnitude and direction) and add according to the parallelogram law.n object's acceleration is the net result of any and all forces acting on the object, as described by Newton's Second Law.
