Question

friction is a force that occurs when one object rubs against another object causing

motion to increase.

resistance to motion.

motion to maintain.

Explanation:

Friction is a force that opposes the relative motion between two surfaces in contact. When one object rubs against another, friction acts to resist that motion. "Motion to increase" is incorrect because friction typically slows things down, not speed them up. "Motion to maintain" is also incorrect as friction doesn't help maintain motion in the sense of keeping it going without external force; rather, it resists it. So the correct description of what friction causes is resistance to motion.

Answer:

B. resistance to motion (assuming the options are labeled A, B, C with A: motion to increase, B: resistance to motion, C: motion to maintain)
