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 is the change in velocity over time. In SI units, acceleration is measured in metres per second squared (m/s2).   g is the symbol for the average accelerat â¦ ion produced by gravity at the Earth's surface. The actual acceleration of gravity varies from place to place, depending on latitude, altitude, and local geology.
