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 can be expressed in the true values of m/sec2 rms or gravitational units âgâ. where 1g is equal to 9.81 m/sec2 approximately. If we want to know the overall velocity of the vibration the instrument can calculate that for. us and read it out in mm/sec rms.
