Suppose you are walking in an airliner in-flight use newtons third law to describe the effect of your work on the motion on the airliner

According to Newton's 3rd law, for every force applied, there's an equal and opposite force that will occur. So when you are walking , you are pushed forward but the plain is "pushed back" from the force

Explanation:

A force is a push or a pull that acts upon an object as a results of its interaction with another object. Forces result from interactions.The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs. According to Newton, whenever objects A and B interact with each other, they exert forces upon each other. A variety of action-reaction force pairs are evident in nature.
