Final answer:
The equation for Newton's second law of motion is F = m * a.
Step-by-step explanation:
Newton's second law of motion states that the net external force (F) on an object with mass (m) is proportional to and in the same direction as the acceleration (a) of the object, and inversely proportional to the mass. Mathematically, this law can be expressed as:
F = m * a
