* Speed is a scalar quantity: It only considers the magnitude (how fast) and not the direction of movement.
* Average speed is calculated by total distance traveled divided by total time: If an object is moving, it covers some distance over a certain time. This means both distance and time will be non-zero values.
Example: Imagine a car traveling 10 kilometers in one hour. Its average speed is 10 km/h, even if it stops and starts during that hour.
Zero average speed implies no movement. If an object's average speed is zero, it means it didn't cover any distance, and therefore, it was not moving.
However, average velocity can be zero. Velocity is a vector quantity, meaning it considers both magnitude (speed) and direction. An object can move in different directions and end up back at its starting point, resulting in a zero average velocity.
