Question

prove that f=ma.
plzz it's urgent​

Answer 1

♣Rate of change of momentum of an object is proportional to the applied unbalanced force

so we have

F proportional to M........(1)

F proportional to A.........(2)

from (1) and (2) we have

$\boxed{\boxed{\underline{\green{\huge{\mathfrak{F=mXa}}}}}}$

$\pink{Note:}$

proportional means

If mass increases the force also increase linearly and same with accelaration.

Answer 2

Answer:

change in momentum=∆p

∆p=m(v-u)/t---------equation1

from 1st equation of motion v-u =at

putting in equation 1

∆p= m a t/t

force =k change in momentum(constant=k)

force=ma
