F=ma ----(i)
force=mass x acc.
F=d(p)/d(t) ----(ii)
force=rate of change of momenta
F2=-F1 ----(iii)
force exerterd by particle 1 on particle 2=force exerted by particle 2 on 1 but in an opposite direction

I assume you are asking about Newton's laws of motion.
-The first law is a statement about inertia and is also called Galileu's law of inertia. You can write it as: if v = constant then F = 0
-The second law is usually written as F = ma where m and a are respectively the mass and the acceleration. The law can also appear in the form F = dp/dt whre p is the linear momentum of the body of mass m and velocity v with p = mv . This is a more general form than F = ma (because this assumes m = const).
-The third law can be stated as Fr = -Fa whre Fa amd Fr are action and reaction respectuively
