Newton's second law states that the force applied in the object depends upon to first is acceleration and the second is mass of the object
F=ma

[tex]\sf\bold\red{{ANSWER:-}}[/tex]
According to Newton's second law of motion the net force experienced by the body is directly proportional to the rate of change of momentum of the body.
It can be written as:-
[tex]\sf\:\implies f ∝\dfrac{dp}{dt}[/tex]
[tex]\sf\:\implies\:f∝\dfrac{mv-mu}{t}[/tex]
[tex]\sf\:\implies\:f∝\dfrac{m(v-u)}{t}[/tex]
[tex]\sf\:\implies\:f∝ma[/tex]
[tex]\sf\:\implies\:f=kma[/tex]
Where k is the constant of proportionality and it comes out to be 1 when the values are taken in SI unit. Hence the final expression will be,
[tex]\sf\:∴F = ma [/tex]
