1 answer

Let's categorize the items you've listed based on their definitions:

  1. Speed: This is the measurement of the distance an object traveled in a specific time. It does not have a direction associated with it.

    • Example: 25 km/hr

  2. Velocity: This refers to speed and direction an object traveled. It is a vector quantity, meaning it has both magnitude and direction.

    • Example: 100 km/hr north

  3. Acceleration: This is the change in speed and/or direction. It quantifies how quickly an object is speeding up or slowing down.

    • Example: Slowing down at a red light (this indicates a decrease in speed, which is acceleration in the negative direction).

Here's the proper alignment:

  • Measurement of the distance an object traveled in a specific time: Speed
  • Slowing down at a red light: Acceleration
  • Speed and direction an object traveled: Velocity
  • 25 km/hr: Speed
  • Change in speed and/or direction: Acceleration
  • 100 km/hr north: Velocity
