What is Newton's Second Law?

It states that the force acting on an object is equal to the mass of that object times its acceleration (F = ma).

What units should I use?

Standard SI units are: Force in Newtons (N), Mass in Kilograms (kg), and Acceleration in meters per second squared (m/s²).

Yes, this law applies to the net force acting on an object.
