What does Newton SI unit of force mean?

Answer 1

1 Newton is the amount of force necessary to accelerate a 1 kg mass at an acceleration rate of 1 meter per second2

Since the acceleration due to Earth's gravitational pull is 9.8 m/s2, a 1 kg mass will exert a 9.8 Newton force against a surface that it is resting on.

Answer 2

The Newton is the SI unit of force, defined as the amount of force required to accelerate a one kilogram mass by one meter per second squared. This unit is commonly used to measure the strength of a force acting on an object.
