The images represent the 3rd law. By when motion moves in one direction the person movesin the opposite motion.

Newton created his laws in the year 1686 ,and he presented his laws to the Principia Mathematica Philosophiae Naturalis. All of his laws stated different statement on how force and gravity can affect an object and how that object moves through other objects. Newton’s 3rd and final law states that a force is a push or pull upon an object which results from its interaction with another object.

What all of this rely means is that every interaction there are a pair of forces acting upon the object with the same force. So when someone sits on a chair that persons body pushes a force down on the chair but the only way that person stays up and doesn’t fall is that the chair pushes upward with a equal force. If you were to push with a force of 10 Newton’s against a wall, the wall would push back with a force of 10 Newton’s.
