# Classify the following measures as scalars and vectors. $20m/s^2$

This question has multiple parts. Therefore each part has been answered as a separate question on Clay6.com

Toolbox:
• A scalar quantity has only magnitude.
• A vector quantity has both magnitude and direction.
Step 1:
We are asked to classify $20m/s^2$ as a vector or a scalar quantity.
$20m/s^2$ measure acceleration of a particle.
We know acceleration has both magnitude and direction.
Step 2:
Hence it is a vector quantity.
