Second Law Of Motion. The second law of motion, first derived by Isaac Newton, states that the acceleration of an object subject to a force is directly proportional to the net force, and inversely proportional to the mass of the object, or a=F/m, where a is the acceleration, F is the net force, and m is the mass.

hey mate!!
second law motion states that the rate of change of momentum is directly proportional to the unbalanced force of applied

here is the derivation of second law of motion

Suppose an object of mass, m is moving along a straight line with an initial velocity, u.
It is uniformly accelerated to velocity, v in time, t by the application of a constant force, F
throughout the time, t. The initial and final momentum of the object will be,
p1 = mu and p2 = mv respectively. 
The change in momentum ∝ p2 – p1
The change in momentum∝ mv – mu
The change in momentum∝ m × (v – u).
The rate of change of momentum ∝ m × (v −u)/t
Or, the applied force,
F ∝m × (v −u)/t
F  = km (v -  u)/t

F = kma 
Here a [a = (v – u)/t ] is the acceleration, which is the rate of change of velocity


hope this helps you!!
