Newton’s 3rd law states: when one object exerts a force on a second object, the second object will exert an equal and opposite force on the first object. If you push an object right then the object pushes you to the left. This is called an action/reaction force. The action/reaction pair is called an interaction. Whatever you do to an object it does the opposite to you. The mass can be changed according to the mass of the object. The bigger the mass means the smaller the acceleration. The smaller the mass means the larger the acceleration.
