Newtons second law of motion

This video that I found on Khan Academy gives a clear definition of Newton’s second law of motion. On it he states the equation most commonly associated with Newton’s second law: f = m x a (net force equals mass times acceleration). This equation can also be translated to a = f/m. But what is this equation really stating? It basically saying that acceleration is dependent on two variables: the net force of an object and the mass of an object.

a~f               Acceleration is directly proportional to the net force of an object

·      If net force decreases acceleration will also decrease.

·      In net force increases acceleration will also increase.

a~1/m        Acceleration is inversely proportional to mass

·      If mass increases acceleration decreases.

·      If mass decreases acceleration increases.
