- | FIXME Rest of definition please | + | The third law states that whenever one body exerts a force on a second body, the second object exerts a force that is equal in magnitude and opposite in direction. $F_a = -F_b$. Note that it is the **force** that is equivalent. With the 2nd law, this means that they can have differing accelerations after the application |
