Speed is how fast an object is moving. It tells you the magnitude (amount) of the motion. Think of it as a speedometer reading.
* Example: A car traveling at 60 miles per hour has a speed of 60 mph.
Velocity is speed with a direction. It tells you how fast an object is moving and in what direction.
* Example: A car traveling at 60 miles per hour *north* has a velocity of 60 mph north.
Key Differences:
* Speed is a scalar quantity, meaning it only has magnitude.
* Velocity is a vector quantity, meaning it has both magnitude and direction.
So, if you know an object's velocity, you automatically know its speed. But if you only know the speed, you don't know the direction of motion.
Think of it this way:
* Imagine you're driving a car. You know your speed (how fast you're going), but you don't know your velocity until you know which direction you're traveling.
