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.
Velocity, displacement [s], momentum, force and acceleration are vectors. 6. Speed, distance [d], time, and energy (joules) are scalar quantities. 7. The slope of the velocity-time graph is acceleration. 8. At zero (0) degrees two vectors have a resultant equal to their sum. At 180. degrees two vectors have a resultant equal to their difference. From the difference. to the sum is the total range of possible resultants.
