Question

How to prove force = mass * acceleration
​

Answer 1

F = Mass X Acceleration

Where F directly proportional to rate of change of momentum

F is proportional to (v-u) / t

If we are removing the proportional then there would be a constant added lets assume the constant as K

F=k(v-u/t)

k is constant so k=1

momentum=mv

f=k(-u/t)mv

f=mk(v-u/t)  since v-u/t =a

f=kma where k is constant

f=ma
