Answer :
Acceleration is defined as the rate of change in the speed of a moving body or vehicle typically.
Explanation:
In the branch of mechanics, the aspect of acceleration is considered to be a property of the vector. And acceleration always occurs in a specific positive direction.
The formula for determining acceleration is change in the rate of velocity over a specific time, and is therefore measured as the ratio of delta velocity by delta time unit.
[tex]\text {acceleration}=\frac{\text {velocity}}{\text {time}}=\frac{\left(\frac{\text {distance}}{\text {time}}\right)}{\text {time}}=\frac{\text {distance}}{\text {time}^{2}}\left(\mathrm{m} / \mathrm{s}^{2}\right)[/tex]
The unit of acceleration is distance per time unit squared or m / second squared.
