Question

7.) read and answer below. use the figure below to answer the questions: which best describes why figure b will have to work harder to get down the hill? a. figure a has more gravity, so it will be easier for him. b. figure b has more friction, so it will be harder for him. c. figure b has no unbalanced forces working on him. d. figure a has more friction, so it will be easier for him. 8.) the difference between the initial (first) position and the final position of an object is called ____. a. motion b. gravity c. displacement d. rocky road 9.) true or false. a test booklet is sitting at rest on a desk. compared to the force of the booklet on the desk, the force of the desk on the booklet is the same. true false

Explanation:

• For the first question, more friction makes it harder to move down a hill. Figure B having more friction would make it harder for him, so B is correct.
• For the second question, displacement is defined as the difference between the initial and final position of an object, so C is correct.
• For the third question, according to Newton's third - law, when a booklet is on a desk at rest, the force of the booklet on the desk and the force of the desk on the booklet are an action - reaction pair and have the same magnitude, so it's True.

Answer:

1. B. Figure B has more friction, so it will be harder for him.
2. C. Displacement
3. True
