* Speed is about change: Speed measures how quickly something is moving. To know the speed, you need to know how much its position changes over a certain amount of time.
* No movement: The object being 10 meters away for 2 seconds could mean it's completely stationary (not moving at all).
To calculate speed, you need:
* Initial position: Where the object starts.
* Final position: Where the object ends up.
* Time taken: The duration of the movement.
Example:
* If the object starts 10 meters away, then moves to 5 meters away in 2 seconds, then you could calculate its speed.
* Change in position: 10 meters - 5 meters = 5 meters
* Speed: 5 meters / 2 seconds = 2.5 meters per second
