* Velocity is instantaneous: Velocity tells you how fast an object is moving at a specific moment in time and in what direction.
* Constant velocity doesn't mean movement: An object with a constant velocity of 0 m/s is not moving.
* Change in position is key: To know if an object has moved, you need to track its position over a period of time.
Here's how to determine if an object has moved:
1. Record its initial position: Note where the object starts.
2. Record its final position: Note where the object ends up.
3. Compare the positions: If the initial and final positions are different, the object has moved.
Example:
* A car with a velocity of 60 km/h is moving.
* A parked car with a velocity of 0 km/h is not moving.
To summarize: Velocity tells you how fast and in what direction an object is moving at a given moment, but it doesn't tell you if the object has actually changed its position over time.
