1. Speed:
* Non-example: A car traveling at 60 mph.
* Why: Speed only tells you how fast something is moving, not in what direction. Velocity needs both speed and direction.
2. Distance:
* Non-example: The distance between New York and Los Angeles is 2,446 miles.
* Why: Distance is a measure of how far apart two points are, not how fast something is moving.
3. Time:
* Non-example: It took 3 hours to drive from home to work.
* Why: Time tells us how long something took, but not how fast it was moving.
4. Acceleration:
* Non-example: A car accelerating from 0 to 60 mph in 5 seconds.
* Why: Acceleration is the rate of change of velocity. While velocity is a component of acceleration, they are distinct concepts.
5. Displacement:
* Non-example: A runner completing a 400-meter track race.
* Why: Displacement is the overall change in position from the starting point. While a runner covers a distance, their displacement could be zero if they end up back where they started.
Remember: Velocity is a vector quantity, meaning it has both magnitude (speed) and direction. Any measurement that lacks either of these components is not a velocity.
