Reading Quiz: Newton's Laws   

Answers must be submitted by 8:00am Monday, January 14th.

Read CP (the blue book by Hewitt) Chapter 4 Sections 6 and 7, Chapter 5 Sections 1-4 and 6, plus all of Chapter 6. Then answer the following questions:

Enter your last name, first initial:  

Click here to indicate that you have read the assigned material and are answering the reading questions on your own.

1.  Suppose that a net force acts on an object. If the net force is doubled, while all other factors are held constant, what happens to the object’s acceleration (does it stay the same, or does it increase or decrease, and by what factor) ? (6 words or fewer)

 

2. Suppose that a net force acts on an object. If the object’s mass is doubled, while all other factors are held constant, what happens to the object’s acceleration (does it stay the same, or does it increase or decrease, and by what factor) ? (6 words or fewer)

 

Questions 3-7 refer to the following scenario. Suppose you exert a force of 200 N on your refrigerator and push it across the kitchen floor at a constant velocity.

3. How much friction force acts on the refrigerator ?

4. What object is making this friction force (one word) ?

5. Is the friction force equal and opposite to your 200 N push (yes or no) ?

6. Which of Newton’s laws must you use to prove all of your answers to questions 3-5 (one word or number) ?

7.  In questions 3-6, explain why the friction force can not be the action/reaction force to your push. (a good answer to this question requires two complete sentences)

 

8. Tell what force is the correct action/reaction force to your push in questions 3-7 (your answer must be in the form "force of blank on blank"). (5 words)

5.  A penny has a mass of 2.5 grams; the mass of a typical bird’s feather is about 0.5 grams. Determine the force of Earth’s gravity on each object.

penny: newtons

feather: newtons

What is each object’s acceleration in free fall ?

penny: m/s/s

feather: m/s/s

Which of Newton’s Laws can be used to calculate each object’s acceleration ? (one word or number)

6. Will hanging a magnet in front of an iron car, as shown, make the car go? Explain briefly, making it clear which of Newton's laws you are using. A good answer requires a complete sentence explanation here.
