Question

HOW MEASURMENT OF FORCE OBTAINED FROM NEWTON SECOND LAW OF MOTION

Answer 1

Force = mass × acceleration is the required relation which gives the measurement if force✌

Answer 2

Newton's second law of motion states that Force is Directly proportional to the change in momentum of an object. Thus,

F ∞ ∆p

F ∞ (mv - mu)/t

Taking m common,

F ∞ m(v - u)/t

=> F ∞ ma

(Since, {v - u}/t = a)

=> F = kma

(where k is the constant)

For 1 Newton of Force applied on an object of mass 1 kg, which produce an acceleration of 1m/s², value of k becomes 1, thus,

F = ma




where, F stands for force, m for mass, a for acceleration, p for momentum, t for time and v and u for final and initial velocity respectively.
