Question

PROOF THAT 1 NEWTON OF FORCE = PRODUCT OF MASS AND VELOCITY​

Answer 1

Answer:

force =m multiplied by a where m is mass of the body having 1 kg and a is acceleration of 1m/s of the body .when we multiply m and a ,we get the dimension of force to me N.thus force means product of mass and acceleration and not the product of mass and velocity.

Answer 2

According to Newton's second law of motion, The rate of change of momentum is proportional to the applied force.

Consider a body of mass m having a velocity u. It's initial momentum= mu.

Suppose a force For acts on the body for time t. Now it's velocity changes to v. so it's momentum becomes mv.

From the first statement,,

F is proportional to (mv - mu) /t

So, F is proportional to m(v-u) /t

But, (v-u) /t = Acceleration(a)

So, F is proportional to ma

Thereby, F = kma(where k is a constant)

In S.I units, k = 1

So, the equation becomes F = ma
