The term equal to velocity change per second is acceleration.
1. Velocity is the rate of change of an object's position with respect to time.
2. Acceleration, on the other hand, is the rate of change of an object's velocity with respect to time.
3. Therefore, acceleration measures how quickly the velocity of an object is changing.
4. Mathematically, acceleration is calculated as the change in velocity divided by the time taken for that change.
5. It is usually measured in units like meters per second squared (m/s²) or kilometers per hour per second (km/h/s).
In the context of the given options, acceleration is the term that specifically represents the velocity change per second.
