Here's a bit more about it:

* What is a force? A force is a push or pull that can change the motion of an object.

* How is a Newton defined? One Newton is the force needed to accelerate a 1 kilogram mass at a rate of 1 meter per second squared.

Other units you might encounter:

* Dyne (dyn): An older unit of force, equal to 10^-5 Newtons.

* Pound-force (lbf): A unit of force commonly used in the United States. 1 lbf is approximately equal to 4.45 Newtons.
