Speed tells you how fast something is moving. It's a scalar quantity, meaning it only has magnitude (amount).
* Example: A car traveling at 60 mph has a speed of 60 mph.
Velocity tells you how fast something is moving and in what direction. It's a vector quantity, meaning it has both magnitude and direction.
* Example: A car traveling at 60 mph eastward has a velocity of 60 mph east.
Here's a simple analogy:
* Imagine you're driving a car. Your speedometer tells you your speed.
* Your GPS tells you your velocity (speed and direction).
Key Differences:
* Direction: Speed doesn't care about direction, while velocity does.
* Change: A change in speed *or* direction means a change in velocity.
* Zero Velocity: An object can have zero velocity (stationary) but still have a non-zero speed (if it's moving in a circle).
In short:
* Speed: How fast?
* Velocity: How fast *and* in what direction?
