* Force: Force has both magnitude (how strong the push or pull is) and direction (the way the object is being pushed or pulled). For example, a 10 Newton force applied upwards is different from a 10 Newton force applied to the right.
* Acceleration: Acceleration also has magnitude (how quickly the velocity is changing) and direction (the direction of the change in velocity). A car accelerating forward is different from a car accelerating backwards, even if the magnitude of the acceleration is the same.
Scalar quantities only have magnitude, while vector quantities have both magnitude and direction.
