An increase in speed or velocity can be described as - acceleration
Acceleration
The change in the rate of the speed or velocity is known as acceleration. It can be increasing speed, changing direction, or decreasing speed. Acceleration is a vector quantity, unlike speed which is scalar.
Acceleration can be calculated by a change in speed or velocity divided by change in time:
[tex]a = \frac{\triangle v}{\triangle t}[/tex].
Where
[tex]\overline{a}[/tex] = average acceleration
[tex]v[/tex] = final velocity
[tex]t[/tex] = elapsed time
