Focus on the Problem. Thus, from Newtons Second Law of Motion, we infer the following: Newtons Second Law of Motion is stated as under:The rate of change of Linear Momentum of a body is directly proportional to the external force applied on the body, and this change takes place always in the direction of the applied force. Thus, Newtons Second Law of Motion connects the change of Linear Momentum of the body with force applied to it and gives the direction in which the change occurs. The third law is also known as the law of action and reaction. What is the biggest problem with wind turbines?

When you jump, your feet apply force to the ground, and the earth applies an equal and opposite reaction force that pushes you into the air. If the only force acting on an object is due to gravity, the object is in free fall. Author: www.physicsclassroom.com. Newtons Second Law of Motion gives the following relation: Here \(F\)is the applied force\({p_i}\) is the initial momentum\({p_f}\) is the final momentum and\(t\) is the time for which the force acts on the body to bring the change in momentum of the body, where,\(m\) is the mass of the body\(u\) is the initial velocity of the body\(v\) is the final velocity of the body and So, the above relation of force becomes, \(F \propto \frac{ {mv mu}}{t}\)\(\therefore \,\,F \propto \frac{{m\left({v u} \right)}}{t}\), where \(a\) is the acceleration produced in the body due to the applied force\(\therefore \,\,F \propto ma\). Impulse of force is the cause of changes to motion and therefore changes to momentum. A force applied to a body can change the magnitude of the momentum or its direction or both.
