Revelant knowledge 

Forces work in pairs. When a force is applied to a body, that body applies an equal force on another body. The directions for force will always be in opposite directions.

Newton’s First Law, often known as”the “law of inertia” which states that an object that is at still remains in place, and an object moving will continue to move in a straight line and at a the same speed, if and only if there isn’t any forces net applying to the object.

Newton’s second law outlines the basic relationship between acceleration of an object that has mass m and net force F _net performing actions on the object

Newton’s third law says that for every action there exists an equally and opposite reaction. The force applied is the action , and the force emitted to the opposing direction another object is called the reaction.
