1. Constant velocity - Traveling with a constant velocity means you're going at the same speed in the same direction continuously.
2. Positive changing velocity - Speeding up means that the magnitude (or numerical value) of the velocity is getting large.
3. Zero acceleration - Zero acceleration is an acceleration, just with zero magnitude.
4. Positive acceleration - is an increasing speed or increasing magnitude of velocity of moving body.
5. Negative acceleration - a negative acceleration means you will subtract from the current value of the velocity.
