Which part of an object's rate of change best defines acceleration?

Marat540 [252]

Answer:

Velocity

Explanation:

The change of velocity rate it's the definition of acceleration.

While increasing or decreasing velocity, it means that an acceleration it's happening.

Using some math:

$a=\frac{dv}{dt}$

This can be read as "the acceleration it's equal to te variation of velocity with respect to time"
