* Vector Quantities: These quantities have both magnitude (size) and direction.
* Acceleration: A change in velocity over time. It has magnitude (like meters per second squared) and direction (e.g., accelerating to the north). YES
* Velocity: The rate of change of position, indicating both speed and direction. YES
* Scalar Quantities: These quantities have only magnitude.
* Speed: The rate of change of position, but without direction. NO
* Temperature: A measure of heat, with only magnitude (e.g., 25 degrees Celsius). NO
* Age: A measure of time elapsed, only a magnitude. NO
In summary: Acceleration and velocity are vector quantities because they have both magnitude and direction. Speed, temperature, and age are scalar quantities because they only have magnitude.
