Acceleration is defined as the rate of change in the speed of a moving body or vehicle typically.
<u>Explanation:</u>
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.

The unit of acceleration is distance per time unit squared or m / second squared.
The answer is kelvin. That is a unit of temperature.
This process helps the necessary areas in the body to get the nutrients the blood carries. this is the curculatory system included with the other systems that creates a type of substance or nutrient the body needs.
