Question

2.3 m/s north is an example of a(n) ------. time acceleration velocity speed

Explanation:

To determine the answer, we analyze the concepts:

• Time: A scalar (duration), no direction.
• Acceleration: Rate of velocity change (vector, but formula \(a = \frac{\Delta v}{\Delta t}\); not matching "2.3 m/s north").
• Velocity: Vector quantity (speed + direction). "2.3 m/s north" has magnitude (2.3 m/s) and direction (north), fitting velocity.
• Speed: Scalar (magnitude only), no direction.

Answer:

velocity
