Everyday Examples:
* A car traveling at 60 mph due east. (Speed = 60 mph, Direction = East)
* A person walking 3 miles per hour north. (Speed = 3 mph, Direction = North)
* A ball thrown straight up at 20 meters per second. (Speed = 20 m/s, Direction = Upward)
* A river flowing at 5 km per hour downstream. (Speed = 5 km/h, Direction = Downstream)
Scientific Examples:
* The Earth orbiting the Sun at approximately 30 km per second. (Speed = 30 km/s, Direction = Along the orbit's path)
* A rocket launching at 25,000 miles per hour eastward. (Speed = 25,000 mph, Direction = East)
* A molecule of oxygen moving at 480 meters per second in a random direction. (Speed = 480 m/s, Direction = Random)
* A light wave traveling at 299,792,458 meters per second. (Speed = 299,792,458 m/s, Direction = Straight)
Key Points:
* Velocity is a vector: This means it has both magnitude (speed) and direction.
* Changes in direction change velocity: Even if the speed is constant, a change in direction changes the velocity.
* Negative velocity: Velocity can be negative to indicate a direction opposite to a chosen positive direction (like going westward when eastward is considered positive).
