Why are the normal force and the force of gravity acting on a book resting on a table NOT considered a Newton's Third Law force pair?

• They are not equal in magnitude.

• They are not opposite in direction.

• They act on the same object.

• They are not simultaneous.

Which of the following represents a Newton's Third Law force pair related to a book resting on a table?

• The normal force of the table on the book and the force of gravity on the book.

• The normal force of the book on the table and the normal force of the table on the book.

• The force of gravity on the book and the force of gravity on the table.

• The normal force of the table on the book and the force of friction on the book.

When a book rests on a table, which pair of forces constitutes a Newton's Third Law force pair involving gravity?

• The force of gravity of the Earth on the book and the normal force of the table on the book.

• The force of gravity of the Earth on the book and the force of gravity of the book on the Earth.

• The force of gravity of the Earth on the book and the normal force of the book on the table.

• The force of gravity of the Earth on the book and the force of friction on the book.

What is a key characteristic of a Newton's Third Law force pair?

• The forces act on the same object.

• The forces are always gravitational.

• The forces act on two different objects.

• The forces are not necessarily simultaneous.
