Question

11) Derive the relation F = ma from newton's 2nd law

Answer 1

Answer:

Explanation:

According to Newton's Second Law:

change in momentum is proportional to p1-p2

~ m1(v1-u1)/t-m2(v2-u2)/t

~m1a1-m2a2=ma

, Force applied externally,

F=kma

, where k is a constant.

F=kma

Now, if, m=1

a=1

then, F=1=k*1*1

thus, k=1

thus, we can take, F=ma

Hence proved
