What are newtons?

Answer 1

Newtons are a unit of force. A force of 1 Newton acting on a mass of 1 kilogram causes it to accelerate by 1 metre/second every second by Newton second law: force = mass x acceleration.

A 1-kg mass that is dropped will accelerate down at 9.81 metres per second per second before it hits the floor, therefore the force acting it, which is its weight, is 9.81 Newtons.

But the same 1-kg mass, on the Moon, accelerates one sixth as fast, and its weight is less, one sixth of the old weight, so its weight is only 1.63 Newtons.

Answer 2

Newtons are a unit of measurement for force in the International System of Units (SI). One newton is equal to the amount of force required to accelerate a mass of one kilogram at a rate of one meter per second squared. It is named after Sir Isaac newton, the renowned physicist.

Answer 3

Newtons are the SI unit of force. One newton is the force required to accelerate a one-kilogram object at one metre per second per second (1kg @ ms-2).
