3. Newton's Laws of Motion describe the way a body responds to applied forces

4. First law: A body remains in a state of rest or uniform motion (constant velocity – constant speed in a straight line) unless acted upon by an external force.

5. Second law: A force F acting on a body of mass m causes an acceleration a in the same direction as the force. F = ma

6. Second law: A force F acting on a body of mass m causes an acceleration a in the same direction as the force. ie The acceleration is proportional to the magnitude of the force and inversely proportional to the mass. F = ma a = F/m

7. F = ma a = F/m

8. F = ma a = F/m a = dx/dt

9. F = ma a = F/m a = dx/dt F = mdx/dt F = dp/dt

10. Thus the Force is equal to the differential of the momentum wrt time F = ma a = F/m a = dx/dt F = mdx/dt F = dp/dt

11. Third law For any action there is an equal and opposite reaction

16. Newton's laws of motion consist of three physical laws that form the basis for classical mechanics. They describe the relationship between the forces acting on a body and its motion due to those forces. They have been expressed in several different ways over nearly three centuries,[1] and can be summarized as follows: physical laws classical mechanicsmotion[1] http://en.wikipedia.org/wiki/Newton%27s_laws_of_motion

[2][3][4] This means that in the absence of a non-zero net force, the center of mass of a body either remains at rest, or moves at a constant speed in a straight line. velocity[2][3][4]net forcecenter of massbodyspeed Second law: A body of mass m subject to a force F undergoes an acceleration a that has the same direction as the force and a magnitude that is directly proportional to the force and inversely proportional to the mass, i.e., F = ma. Alternatively, the total force applied on a body is equal to the time derivative of linear momentum of the body.mass accelerationtime derivativemomentum Third law: The mutual forces of action and reaction between two bodies are equal, opposite and collinear. This means that whenever 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. This law is sometimes referred to as the action-reaction law, with F called the "action" and −F the "reaction". The action and the reaction are simultaneous.action-reaction law
