1.Choosing a frame of reference requires deciding where the object's initial position is and which direction will be considered positive. Valid frames of reference can differ from each other by moving relative to one another. Frames of reference are particularly important when describing an object's displacement.
2.According to Newton's third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.
