This is stated as ''F=ma'' which means the ''force'' (F) acting on an object is equal to the ''mass'' (m) of an object times its [[acceleration]] (a). | This is stated as ''F=ma'' which means the ''force'' (F) acting on an object is equal to the ''mass'' (m) of an object times its [[acceleration]] (a). | ||
This is an immutable law of physics which holds in all non-relativistic, non-quantum scales. But the conditions in which it operates — zero friction, perfect elasticity, non-intertial frame of reference — circumstances which never exist in real life. So a rolling ball with no force acting upon it will eventually stop. A [[crisp packet blowing across St. Mark’s square]] still does obey Newton’s laws of motion, but good luck calculating its trajectory using them. | This is an immutable law of physics which holds in all non-relativistic, non-quantum scales.
