Question

Please friends give me derivation of Newton's second lae

Answer 1

: Newton's second law of motion describes the relationship between an object's mass and the amount of force needed to accelerate it. Newton's second law is often stated as F=ma, which means the force (F) acting on an object is equal to the mass (m) of an object times its acceleration (a).

Answer 2

According to Newton's law, force is directly proportional (d.p.) to change in momentum upon time
d.p. mv-mu/t
d.p. m(v-u)/t
d.p. ma
=k*m*a
if k is any constant,then
f= m*a
