Define one newton of force.


Open in App
Solution

  1. Newton is the SI unit of force.
  2. From Newton's second law of motion, we have

F=ma(wheremisthemassofthebodyandaistheacceleration)

3. If m=1kganda=1ms-2, then,

F=1kg×1ms-2=1newton

4. Hence One newton is defined as the force that is required to accelerate a mass of 1kgby 1ms-2 in the direction of applied force.
