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 rate of change of the velocity vector, , which expresses itself as the slope of the velocity vs. time graph. For a velocity vs. time graph, the acceleration at time t is equal to the slope of the line at t. What is the acceleration of our ant at t = 2.5 and t = 4? Looking quickly at the graph, we see that the slope of the line at t = 2.5 is zero and hence the acceleration is likewise zero.
