* Velocity:
* Magnitude: The speed of an object, which tells you how fast it's moving (e.g., 20 meters per second).
* Direction: The direction the object is moving (e.g., north, east, or 30 degrees above the horizontal).
* Acceleration:
* Magnitude: The rate at which the velocity is changing, which tells you how quickly the object is speeding up or slowing down (e.g., 5 meters per second squared).
* Direction: The direction of the change in velocity. If the object is speeding up, the acceleration is in the same direction as the velocity. If the object is slowing down, the acceleration is in the opposite direction of the velocity.
Example: Imagine a car traveling at 60 mph east. This describes its velocity. If the car accelerates to 70 mph east, the acceleration is in the same direction (east). But if the car brakes and slows down to 50 mph east, the acceleration is in the opposite direction (west).
In summary: Because velocity and acceleration have both magnitude and direction, they are considered vector quantities.
