* Speed is a scalar quantity, meaning it only tells us how fast something is moving. It doesn't care about the direction.
* Example: A car traveling at 60 mph.
* Velocity is a vector quantity, meaning it tells us both how fast something is moving *and* in what direction.
* Example: A car traveling at 60 mph eastward.
Here's a table summarizing the key differences:
| Feature | Speed | Velocity |
|--------------|----------------------------------------|-----------------------------------------|
| Quantity | Scalar | Vector |
| Direction | Doesn't consider direction | Includes direction |
| Example | 60 mph | 60 mph eastward |
Think of it this way:
* If you're driving on a highway, your speedometer tells you your speed.
* If you're giving directions to someone, you need to tell them both your speed and the direction you're going (e.g., "Take the highway north for 20 miles").
In summary:
* Speed is how fast you're going.
* Velocity is how fast you're going *and* which way you're going.
