Answer: A. acceleration

Explanation: Acceleration is the term that is equal to velocity change per second. Acceleration refers to the rate at which an object's velocity changes over time. It measures how quickly an object's speed or direction changes. When an object speeds up, slows down, or changes direction, its velocity is changing, and this change per unit of time is known as acceleration.

To calculate acceleration, you divide the change in velocity by the time it takes for that change to occur. The unit of acceleration is meters per second squared (m/s²) in the metric system. For example, if an object's velocity changes from 10 m/s to 20 m/s in 2 seconds, the acceleration would be (20 m/s - 10 m/s) / 2 s = 5 m/s².
