The rate of change of momentum of body is directly proportional to the force,and the body moves in the direction of force applied.

Newton's third law of motion is that for every action there is an equal and opposite reaction. This law is also called reciprocal motion/force or "action-reaction."
*
Newton's Second law is: F=ma Force is the product of mass times acceleration. Newton's Third law is : At Equilibrium Condition, For every Action there is an equal and opposite Re-Action.
I believe it's Newtons second law because, the definition of Newtons second law is : An object acted by a force will accelerate in the direction of the force. When you push someone if you push hard enough their body will move in the direction they were pushed or forced to go or travel.
Newton's first law is to define force Second law to measure force Third law to know about nature of force What about fourth law? I have not heard about it. May be your expectation with gravitation
newtons third law of motion
NEWTONS THIRD LAW OF MOTIONWhenever a first body exerts a force F on a second body, the second body exerts a force −F on the first body. F and −F are equal in magnitude and opposite in direction.Example: seatbelts
Always. Evey object in the universe is experiencing Newtons third law. Just by sitting in your chair motionless you are experiencing Newtons third law.
