d) The reaction to the force in Part A is a force of magnitude _____, exerted on the _____ by the _____. Its direction is _____ .

Front

5 N / earth / book / upward

Back

The two forces in each pair can act on the same object or on different objects.

Front

false

Back

c) Do the downward force in Part A and the upward force in Part B constitute a 3rd law pair?

Front

no

Back

Every force has one and only one 3rd law pair force.

Front

true

Back

According to Newton's 3rd law, the force on the (smaller) moon due to the (larger) earth is: - greater in magnitude than, and in the opposite direction from, the force on the earth due to the moon. - greater in magnitude than, and in the same direction as, the force on the earth due to the moon. - equal in magnitude to, and in the opposite direction from, the force on the earth due to the moon. - equal in magnitude to, and in the same direction as, the force on the earth due to the moon. - smaller in magnitude than, and in the opposite direction from, the force on the earth due to the moon. - smaller in magnitude than, and in the same direction as, the force on the earth due to the moon.

Front

equal in magnitude to, and in the opposite direction from, the force on the earth due to the moon.

Back

The two forces in each pair may have different physical origins (for instance, one of the forces could be due to gravity, and its pair force could be a normal contact force).

Front

false

Back

The two forces of a 3rd law pair always act on different objects.

Front

true

Back

a) A downward force of magnitude 5 N is exerted on the book by the force of

Front

gravity

Back

The two forces in each pair act in opposite directions.

Front

true

Back

Given that two objects interact via some force, the accelerations of these two objects have the same magnitude but opposite directions. (Assume no other forces act on either object.)

Front

false - Newton's 3rd law can be summarized as follows: A physical interaction (e.g., gravity) operates between two interacting objects and generates a pair of opposite forces, one on each object. It offers you a way to test for real forces (i.e., those that belong on the force side of ∑F⃗ =ma⃗ )—there should be a 3rd law pair force operating on some other object for each real force that acts on the object whose acceleration is under consideration.

b) An upward force of magnitude _____ is exerted on the _____ by the table.
