Detailed explanation-1: -Newton s Third Law When one object exerts a force on another object, the second object exerts a force on the first object that is equal in magnitude, but opposite in direction; for every action, there is an equal, but opposite reaction; called the law of action-reaction.
Detailed explanation-2: -Newton’s third law of motion states that whenever a first object exerts a force on a second object, the first object experiences a force equal in magnitude but opposite in direction to the force that it exerts.
Detailed explanation-3: -In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
Detailed explanation-4: -During swimming, a swimmer moves ahead. The water pushes back on the swimmer as the swimmer pushes against it.
Detailed explanation-5: -Mathematically, if a body A exerts a force →F on body B, then B simultaneously exerts a force −→F on A, or in vector equation form, →FAB=−→FBA.
