Newton (unit) 1  1 N is the force of Earth's gravity on an apple with a mass of about 102 g. 2  On the Earth's surface, a mass of 1 kg pushes on its support with an average force of 9.8 N. 3  1 Newton is equal to the amount of force required to accelerate an object at a rate or 1 metre per second, every second.
