Final answer:
When a constant horizontal force is applied to a crate sliding on a factory floor and it exceeds friction, the crate's velocity will be increasing. If the force is balanced by friction, the crate will move with a constant velocity. The question pertains to high school physics and involves concepts such as acceleration, velocity, and Newton's laws of motion.
Step-by-step explanation:
The question is related to an object (a crate) being subjected to a constant horizontal force while sliding on a factory floor, which is a topic generally covered in high school physics. If a constant force is applied and no other forces are changing (assuming friction remains constant), the velocity of the crate will be increasing, as long as the force applied is greater than the frictional force opposing the movement. This situation corresponds to the object experiencing a net force in the direction of movement, resulting in positive acceleration, as per Newton's second law of motion. This principle also applies to the concept of impulse, which suggests that the impulse would be increasing during this period because the force is applied over a period of time, adding to the object's momentum.
When the applied force is exactly balanced by friction, the crate would move with a constant velocity, and the acceleration would be zero. If acceleration is zero over some time interval, according to the definitions of kinematics, the average velocity would be constant.
The overall concept involved is that the application of a constant force on an object will change that object's velocity, assuming that the force exceeds any opposing forces. If the opposing forces are equal to the applied force, the object will continue to move at a constant velocity. If there is no net force, the velocity remains constant or zero if the object is at rest.
