A scalar unit is a unit that has only magnitude, which is a numerical value, as opposed to a vector unit which has both magnitude and direction. Scalar units can be negative, however not all scalar units are capable of this. Some good examples of scalar units are time, distance, speed, volume, and many more. twitch robdiesalotWebA vector is a quantity with magnitude and direction. Some quantities such as mass don't have a direction and are known as scalars. However, velocity is a vector quantity because it has a magnitude called speed and also direction (i.e., the direction an object is travelling). Force is also a vector quantity. take zantac with or without food

"WebAverage Acceleration. Average acceleration is the rate at which velocity changes: a – = Δ v Δ t = v f − v 0 t f − t 0, 3.8. where a − is average acceleration, v is velocity, and t is time. (The bar over the a means average acceleration.) Because acceleration is velocity in meters per second divided by time in seconds, the SI units for ... " - Scalar of acceleration
