The statement that best describes force is:
**Force is a vector quantity that measures both direction and magnitude of a push or pull on an object.**
This accurately reflects that force has both a direction and a magnitude, distinguishing it as a vector quantity.

The best description of the result of the collision is:
**The stationary soccer ball will begin moving downfield and the ball that struck it will slow down.**
In a typical elastic collision, the moving soccer ball transfers some of its momentum to the stationary ball, causing the stationary ball to move in the same direction (downfield) while the initially moving ball slows down.
**The stationary soccer ball will begin moving downfield and the ball that struck it will slow down.**
In a typical elastic collision, the moving soccer ball transfers some of its momentum to the stationary ball, causing the stationary ball to move in the same direction (downfield) while the initially moving ball slows down.

The scenario that accurately describes magnitude and direction is:
**A car traveling northward with 5 kN of force could be brought to a stop by a southward force of 5 kN.**
In this case, the southward force of 5 kN would exactly counteract the northward force of 5 kN, bringing the car to a stop.
**A car traveling northward with 5 kN of force could be brought to a stop by a southward force of 5 kN.**
In this case, the southward force of 5 kN would exactly counteract the northward force of 5 kN, bringing the car to a stop.
