Question

What is one newton??​

Answer 1

it is equal to the force that would give a mass of one kilogram an acceleration of one meter per second and is equivalent to 100,000 dynes.

Answer 2

Answer:

1 N force is that force that is required to move a body of mass 1 kg with an acceleration of  m/s².

Explanation:

According to the Newton’s 2nd Law of motion, the rate of change of linear momentum of a body is directly proportional to the applied external force and in the direction of force.

Derivation:

Consider a body of mass ‘m’ moving with velocity v.

The linear momentum of a body is given by:

p = mv

Now According to Newton’s 2nd Law of Motion:

Force is directly proportional to rate of change of momentum, that is

F ∝ dp/dt

F  = k dp/dt

F = k d(mv)/dt

F = k md(v)/dt

F = k ma

Experimentally k =1

So, we have F = ma

In terms of SI units, we have

1 N = 1 kg / 1 m/s²

Thus, I N force may be defined as:

1 N force is that force that is required to move a body of mass 1 kg with an acceleration of  m/s².
