Question 3 • Physics in the Universe

Two objects are interacting, but stay stationary. Which best describes what is happening to the action and reaction forces?

Answer
A
Their forces are occurring at different times.
B
There are no forces acting on the objects.
C
One object is exerting more force than the other.
D
The forces are equal and opposite each other.

Explanation

By Newton’s third law, interacting objects exert forces on each other that are equal in magnitude and opposite in direction. The objects can stay stationary if other forces balance the interaction forces, so being stationary does not mean there are no forces. The best choice is “The forces are equal and opposite each other.”
