Difference Between Acceleration and Velocity By: Connie Appiah
Acceleration Acceleration is the change in an object’s velocity over time. The equation for acceleration is: To be more specific it is:
Positive Acceleration If your velocity is changing in the negative direction, and the velocity is negative. ( -,-=+) If your velocity is changing in the positive direction, and the velocity is positive. (+,+=+)3
Negative Acceleration Increases speed when moving in negative direction. Decreases its speed when moving in a positive direction Moves in a direction opposite of the positive direction.
Why Speed is not Acceleration Speed is a SCALOR (magnitude) Acceleration is VECTOR (magnitude and direction) Speed is the distance traveled in one unit. Acceleration is change in velocity over time.
Why Velocity is Not Acceleration Velocity? Velocity is speed with a direction. So it has the same formula for speed which is: Change in distance/ change in time but with DIRECTION. Acceleration is the change in velocity in time. While velocity is change in DISTANCE over time acceleration is change in VELOCITYover time.
