Which term is defined as "a change in velocity?"*5 pointsFORCESPEEDSCALARVECTORVELOCITYACCELERATION

Break Down the Problem

1. Identify the key concept being described in the question: "a change in velocity."
2. Consider the possible term options provided: FORCE, SPEED, SCALAR, VECTOR, VELOCITY, and ACCELERATION.

Relevant Concepts

1. Velocity is a vector quantity that refers to the speed of an object in a specific direction.
2. A vector is a quantity that has both magnitude and direction.
3. Speed is a scalar quantity that refers only to how fast an object is moving, regardless of direction.
4. Acceleration is defined as the rate of change of velocity over time.

Analysis and Detail

1. Given that velocity is changing, the most relevant term related to a change in velocity is acceleration.
2. Acceleration is calculated as: $a = \frac{\Delta v}{\Delta t}$ where $\Delta v$ is the change in velocity, and $\Delta t$ is the time during which the change occurs.

Verify and Summarize

1. Acceleration is directly linked to changes in velocity; hence, it is indeed the correct term that describes "a change in velocity."

Final Answer

The term defined as "a change in velocity" is ACCELERATION.
