* Speed: The symbol for speed is usually "v" (lowercase). Sometimes it's written as "s".
* Velocity: The symbol for velocity is also usually "v" (lowercase), but it's often written in boldface (v) or with an arrow above it (v). This is to indicate that velocity is a vector quantity, meaning it has both magnitude (speed) and direction.
Important Note: While both use the same symbol, it's crucial to understand the difference:
* Speed is the rate at which an object covers distance. It's a scalar quantity, meaning it only has magnitude.
* Velocity is the rate at which an object changes its position. It's a vector quantity, meaning it has both magnitude (speed) and direction.
For example, if a car travels at 60 mph, that's its speed. But if the car travels 60 mph eastward, that's its velocity.
