Answer:
Speed
Explanation:
- Speed is a scalar quantity that represents the rate of change of distance. It is calculated as
[tex]v=\frac{d}{t}[/tex]
where
d is the distance travelled by the object (regardless of its direction)
t is the time elapsed
The speed is measured in meters per second (m/s). We can also notice that speed is different from velocity: in fact, speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude+direction).
