Final answer:
Mass cannot be changed by applying a force, while direction, speed, and velocity can be changed.
Step-by-step explanation:
The property that cannot be changed by applying a force to an object is mass. Mass is the quantity of matter an object possesses and it remains constant regardless of the force applied to it.
On the other hand, a force can change the direction, speed, and velocity of an object. Direction refers to the path an object takes, speed refers to how fast an object is moving, and velocity refers to the speed and direction of an object's motion.
