Answer: 1. If the net force of an object is 0 N, the forces are considered unbalanced. B) false 2. most people in the United States use feet and miles to measure distance in their everyday lives. Why do scientists in the United States use meters to measure distance? C) all scientists use meters to measure distance to help eliminate confusion. 3. which of the following forces causes a feather to fall slower than a bowling ball? D) air resistance. 4. a small fish in the Pacific ocean watches a shark swim by a large Rock a few meters away. Which of the following is the reference point in this scenario? B) large Rock 5. which of the following pairs of objects would have the strongest gravitational pull? D) the two stars very close to each other 6. A maglev train uses powerful magnets to lift the train above the tracks as it moves Forward. Such a desire reduces which of the following forces? A) rolling friction 7. which of the following examples does not demonstrate a change in velocity? B) a cruise ship travels West at a constant speed 8. which of the following does not need to be measured in order to describe motion? A) size of the object

Explanation:I just took this ( Friction and Gravity Quiz. Glad I didn't just go off of the answers above. The last question I had to research and I'm not sure about yet because it has not been graded. But I got a 8/8 on the rest of the questions
