Force units are measurements of the amount of force applied to an object. The two most common force units are Dynes and Newtons. Dynes are a unit of force equal to the force required to accelerate a mass of one gram at a rate of one centimeter per second squared. Newtons are a unit of force equal to the force required to accelerate a mass of one kilogram at a rate of one meter per second squared. Both units are used in physics and engineering to measure the amount of force applied to an object.
