4.2.1 Free Body Diagrams Learning Goal: To understand Newton's third law. As shown, a book weighing 5 N lies on a table.( Figure 1) Part C Do the downward force in Part A and the upward force in Part B constitute a third law pair? View Available Hint(s) yes Figure Part A 1 of 1 A downward force with a magnitude 5 N is exerted on the book by the force of Part B the table gravity inertial no Part E The reaction to the force in Part B is a force of magnitude the Its direction is exerted on the by 5 N/table/book/ upward 5 N/book/table/upward O 5 N/table/book/downward O 5 N/earth/book/downward O 5 N/table/earth/upward Part F Which of Newton's laws dictates that the forces in Parts A and B are equal and opposite? Newton's first or second law Newton's third law An upward force with magnitude is exerted on the by the table. Part G 6 N/ table 6 N / book 5 N/ book 5 N / table Which of Newton's laws dictates that the forces in Parts B and E are equal and opposite? Newton's first or second law Newton's third law
