# Vector Quantities - Scalar Quantities

###### Explanation

A scalar quantity contains a magnitude and operates independently of direction while a vector quantity contains a direction. Most scientific data are scalar. A few examples of scalar quantities include time, mass and speed. Examples of vector quantities include velocity and displacement.

Okay how are vector is different from scalar quantities? Well letÃ¢Â€Â™s talk about vectors again. Vectors have a magnitude and a direction so examples that we talk about as vectors are things like velocity meters per second east or acceleration 9.8 meters per second squared you know in the 180 degree direction okay? So vectors have a magnitude and a direction.

Scalar quantities are things that just have a magnitude or an amount so something like a mass in kilograms or a volume in meters or other quantities like that densities and so forth so these are units that donÃ¢Â€Â™t have a direction but they do have a have a magnitude or an amount and thatÃ¢Â€Â™s the difference between a vector and a scalar quantity.
