According to Newton's second law of motion, 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.

Newton’s second law of motion
_____________________________________________________________
<> Momentum, denoted p, can be defined as:
p = mass × velocity = mv
<> Momentum is a vector quantity and is expressed in SI units by kg m s−1 or equivalently by N s.
<> Newton’s second Law of Motion states that:
The rate of change of momentum of a body is proportional to the resultant force acting on it and takes place in the direction of that force.
<> Newton’s second law can be written as :-
F = d dt(mv)
<> For bodies with constant mass, this reduces to F = m d dt(v) = ma , where F = force (N), m = mass (kg), and a = acceleration (m s−2 ).
