* Speed vs. Velocity:
* Speed is the magnitude (amount) of how fast an object is moving. It's a scalar quantity, meaning it only has size.
* Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.
* Zero Speed: If a particle has zero speed, it means it's not moving at all. This implies that its magnitude of motion (speed) is zero.
* Non-Zero Velocity: If a particle has non-zero velocity, it means it is moving in a specific direction. This implies that it has a non-zero speed, as speed is the magnitude of velocity.
In Conclusion: Since speed is the magnitude of velocity, if speed is zero, then the magnitude of velocity must also be zero. Therefore, a particle cannot have zero speed and non-zero velocity simultaneously.
