Newton`s Second Law
... Newton's second law is the relationship between an object's rate of velocity change, the forces acting on that object, and the object's resistance to changing its velocity. The rate of velocity change is called the object's acceleration. Acceleration has units of m/s2. Newton's second law is a mathe ...
