Explain the value or importance of using the international system of units when describing motion.

SI is the International System of Units. SI comes from the French Système international. Motion is physical term that describes movement as the change in position of an object with the time. The basic formula for motion is: F=ma, where m is the mass of the object and a is the acceleration. With the help of the basic units we can obtain the  unit for acceleration and for motion.
The unit for motion is N (Newton). According the formula for motion:
1N= 1kgms-2.
