If you would hit somone u r using a force on another object, the person you hiy exerts a force equal to the oppsite on the person who hit them? Is that right?
if you drag somebody across the room or something, the person being dragged is the reaction force, and the person draging them is the action force
An example of Newton's third law could be that an airplane pushes back on the air and the air pushes forward on the plane.
Newton's Third Law is when someone or something preforms a force te same force will come back at you.
there is an action and reaction, with every force applied there needs to be a reaction to balance out the forces
