Speed:
* Scalar quantity: It only has magnitude (how fast).
* Measures how fast an object is moving.
* Doesn't care about direction. A car traveling at 60 mph, regardless of direction, has a speed of 60 mph.
Velocity:
* Vector quantity: It has both magnitude (how fast) and direction.
* Measures the rate of change of an object's position.
* Takes direction into account. A car traveling at 60 mph east has a different velocity than a car traveling at 60 mph west.
Relationship:
* Speed is the magnitude of velocity. This means if you know the velocity of an object, you can find its speed by simply taking the absolute value of the velocity.
* Velocity is speed with a direction. If you know the speed and direction of an object, you know its velocity.
Example:
Imagine a car traveling at 60 mph east.
* Speed: 60 mph
* Velocity: 60 mph east
In summary:
* Speed is how fast you are moving.
* Velocity is how fast you are moving in a specific direction.
Think of it this way: If you're driving, your speedometer tells you your speed. Your GPS tells you your velocity (speed and direction).
