Question

1. what is the definition of acceleration? the change in speed the change in velocity multiplied by the time of change the change in velocity divided by the time during which the change occurs the change in velocity

Explanation:

Acceleration is a vector - quantity defined as the rate of change of velocity. Mathematically, $a=\frac{\Delta v}{\Delta t}$, where $a$ is acceleration, $\Delta v$ is the change in velocity, and $\Delta t$ is the time interval over which the change occurs.

Answer:

The change in velocity divided by the time during which the change occurs
