Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
Newton's second law: Law of Motion
The rate of change of momentum of a body is equal to the resultant force acting on the body and is in the same direction.
Newton's second law as originally stated in terms of momentum p
“An applied force is equal to the rate of change of momentum”.

An applied force is equal to the rate of change of momentum

The physical meaning of this equation is simply a mathematical definition of a force (rate of change of momentum is called a force).
where
F is the force
p is the momentum
t is the time
v is the velocity
m is the mass
a = is the acceleration.
When the mass m, of the object is constant, the mathematical result of differentiation of momentum becomes simply:

for constant mass

If the mass m is measured in kilograms and the acceleration a is measured in meters per second squared, then the unit of force is kilogram × meter/second squared. This unit is called the Newton: 1 N = 1 kg x 1 m/s².
