What occurs to the velocity of an object when it experiences a net force?

When an object experiences a net force, it is undergoing acceleration according to Newton's second law of motion, which states that force equals mass times acceleration (F = ma). This law implies that if there is a net force acting on an object, the object will not maintain its current state of motion unless that force is zero.

In simpler terms, the net force causes a change in the object's velocity; this change can be an increase in speed, a decrease (which would be negative acceleration), or a change in direction. The key aspect of the question is the implication of "net force," which guarantees that the velocity will change.

Therefore, when a net force is acting on an object, it tends to increase the object's velocity in the direction of the net force, making the correct answer appropriate in this context. This understanding also highlights how motions can vary under different conditions of force applied, including the potential for velocity to decrease if the net force opposes the current motion.
